1. Introduction

You will find a large collection of free applications for molecular biology and chemistry through Internet servers and from other sources. Most of these are written by biologists, chemists, and software developers, sometimes as part of a university or government funded project, sometimes as an unfunded project. Some of these offer a single function useful to you, but one that may be found nowhere else.

What is free software for bioscientists, and especially where can you get it? How do you set it up and use it? What are some good programs, and what overall is available? These are some of the questions you can find answers to in this review, which concentrates on software for molecular biology for the commonly used Macintosh and Microsoft (Wintel) operating systems.

What you won't find answers to here include the many free programs that now run as an Internet service through your web browser. Neither listed are programs available mainly as source code (not ready to run) or Unix programs, nor the choices you have with commercial software, nor software for related areas of chemistry, medicine, population biology, ecology and others.

1.1 Free or commercial software?

Free data analysis software is common in the sciences, as the scientists in need of new analyses develop algorithms for it, then crystallize the algorithms as software. Most of the basic biosequence analyses are scientist-developed, including FastA, BLAST, Clustal, MFOLD, PHYLIP, Paup, CAP, to name a few. The source code of these is often shared freely. But often these algorithm programs lack ease of use and integration with other functions. Commercial software developers have incorporated such algorithms, along with their own, and added a much greater usability and integration, to allow you to analyze your data without spending oodles of time learning how to run the programs.

Besides adding integration and user-interface, companies add the great value of good documentation, telephone and other support for their wares. When your funds permit, and a commercial package does what you need, it is usually a better choice than free software. Given market place realities, companies charge what seem large fees to you, but these fees are needed to cover the many aspects of publishing: advertising, technical support, software developers, and so forth.

For scientists with limited budgets, students and teachers, free software is often the only choice. You can also find unique programs that do things no commercial package does. Another great advantage of free software is that it often includes source code you can use to modify and extend an analysis.

Today with the rapid growth in the fields of bioinformatics and biocomputing, more good programmers are developing software, many making it freely available. You will find more sophistication in attention to user interfaces and ease of your learning to use the software. Still there is no common means for funding development of free software: government agencies do not generally fund projects from individual research/programmers, the main source of many of the free software packages. The shareware concept of users paying for software they use has never worked well. For most scientific software, the potential market is so small that we see a strong distinction between expensive commercial packages and free software.

Usability of free programs is variable, and depends in part on your computer and needs. Be aware that older programs may fail to work on new computers. Tolerance for program flaws and limitations is generally needed, and self-reliance in learning how they work. Often the authors either cannot be contacted, or do not have time to spare for supporting a product that they freely distribute.

1.2 Internet sources

Access to and use of the Internet has become so ubiquitous in our society, especially among scientists, that it is assumed you have or can get such access. This wasn't true a few years back, but since the 1980s, free software for biosciences has been most widely available through the Internet, since distribution that way is free (from cost and time) to software authors. There are a few widely used archives of biosciences software, and today many authors prefer to provide their own network server to distribute software, as that is very easy to do. Archives which collect such software still play an important role in providing these collections, and in archiving them for years past when an author may be able to.

Two commonly used archives of molecular biology software are IUBio Archive, at Indiana University, and the European Bioinformatics Institute (EBI) software archive. Internet resource locators (URLs) for these are

EBI at http://www.ebi.ac.uk/ or ftp://ftp.ebi.ac.uk/

The European Bioinformatics Institute, home to EMBL databank and others, and a home to a large molecular biology software archive, including the very useful Bio Catalog of software (http://www.ebi.ac.uk/biocat/biocat.html).

IUBio at http or ftp://iubio.bio.indiana.edu/

IUBio Archive is home to a large collection of biology software, and also provides services for keyword searching of current GenBank, SwissProt and PIR databanks, and the useful Bionet network news archive. It has been operating since 1989, as a user- and author- supported self-service archive. The molecular biology software collection at IUBio is also mirrored (copied) to sites around the world, including the Finland, Sweden, Japan, United Kingdom, France, Spain, and Israel. See the following software listings section for URLs to these.

A few of many other Internet servers of note include

http://www.ncbi.nlm.nih.gov/ - home site for up-to-date access to Entrez software (databank lookups), Sequin for publishing your sequence in GenBank, Macaw (multiple alignment), and others.

http://kiwi.imgen.bcm.tmc.edu:8088/search-launcher/launcher.html - Search Launcher at Baylor College of Medicine, home to a selection of sequence analysis methods. Recommended is their search launcher program (a Perl script that is usable on Macintosh and Wintel systems) for batch access to this valuable resource.

http://expasy.hcuge.ch/ - home of SwissProt, ProSite and home to a collection of useful database analyses functions, especially for protein data.

1.3 Fetching software

File Transfer Protocol (FTP) is an Internet service designed specifically for file transfer. It is an antecedent of the popular Hypertext Transport Protocol (HTTP), or web, Internet method. Generally FTP is still a better method for transferring large files such as software packages, than is a web browser. One popular and easy to use FTP program for MacOS is the Fetch program by Jim Matthews of Dartmouth College. Find more information at http://www.dartmouth.edu/netsoftware/fetch.html. The ubiquitous Netscape or other web browser also lets you fetch software either via HTTP or FTP methods.

Generally software is stored and transferred to you in encoded formats from archives. Most current fetching software, like Fetch and Netscape, will decode this automatically for you. However, other software sometimes is used or needed for decoding. General Internet software packages and servers will get you started on what is needed. If in doubt, your local library or bookstore will have a few shelves full of books on using Internet services and general software archives.

The main trick in fetching software these days is knowing where to look. Besides this review, you can make use of web links made by others, perhaps with better perspective than this author. See also the common Internet search services, like Yahoo (http://www.yahoo.com/), AltaVista (http://www.altavista.digital.com/), Lycos (http://www.lycos.com/) or others.

Keep in mind that software is updated; if the version you try fails in some way, a newer version may be available now or soon. The author's preferred or home server is the best place to check for updates, as archive servers don't always have the current release.

1.4 Setup and use

Once on your computer, the steps of installing and configuring free software range from easy to trying. Instructions are usually included, but are not always detailed enough, or cover all the range of problems one can run into. Special installing software is common with commercial software, but not with the free variety.

Report problems you have to the author, and suggestions for improving the software. Asking the frequently overworked authors for help with installation isn't always good solution though, so attention to their pre-written installation directions is essential.

Special kinds of software, especially those written for Java or Perl, will require that you also fetch and install other free, general software to use. In the case of Java, this is becoming less a problem as new MacOS and UNIX systems are shipping with a Java runtime as part of the system.

1.5 Multi-platform software

By 1998 counts of Internet browser contacts at IUBio and other biology web servers, from 30% to 50% of biologists use Macintosh computers, 40% to 70% use Wintel systems, with somewhat less than 10% using XWindows systems as their workstation (though many use UNIX or VMS for other things). Bioscientists remain diverse in their computing system choices and needs for software. Many use or have access to multiple operating systems, depending on what software runs on. Also of help, there are commercial emulator programs that allows one to run most MS Windows and MSDOS software on Macintoshes, and conversely to run some Macintosh programs on Wintel systems

Some software is written to run on many operating systems. This may be a holy grail of those who develop scientific applications - one hopes a program can be used by anyone needing it, on any computer system. It isn't as easy to write multi-platform software as might be. Outside of the recent arrival of Java, there hasn't been an easy, good way to do this inexpensively. Even large commercial developers expend effort that is not always successful (e.g., WordPerfect on UNIX pales compared to the MacOS or Wintel versions).

With the case of graphical interface software that most of us expect today, multi-platform programs may not look quite right on your particular system, even though they operate as intended. In the more common case of software with no graphical interface, you may need to devote extra time to learning its command-line or menu driven syntax.

The new Java development system born at Sun Microsystems (http://www.javasoft.com), now is providing a means for developing useful software that works well on common systems, albeit at present Java software is frequently slower than its counterpart written in C++, C or other languages. We may expect to see much more software in biocomputing written in Java in coming years. See for instance the new sequencing analysis package from Licor (www.licor.com).

1.6 Client-Server biosequence software

There are various developers working on the concept of separating the user interface from the analysis programs, and I think this is be a useful approach to making such programs easier to use. This is the basis of a client-server design for software. Simple examples of this are web interfaces that abound now for various data analyses.

This author's own work-in-progress SeqPup takes this approach: it allows you to use the analysis software you need, whether Clustal, CAP, tacg, fastDNAml, or others, running on your own computer or on a server computer. SeqPup provides a graphical interface and standard user interface methods for editing sequences, basic manipulations and alignments, and sophisticated display and output options. It also links to analysis "engines" in a way you can configure to your taste. These analysis programs encode the complex data analysis algorithms but generally without a user-interface beyond command-line options. With a client program such as SeqPup, use of these programs is simplified and tied into a way for you to organize your sequence data.

Martin Senger at EMBL/EBI is working on a general CORBA interface to sequence analysis software called AppLab (http://industry.ebi.ac.uk/applab/), which is a similar approach.

Peter Rice's EMBOSS (http://www.sanger.ac.uk/Software/EMBOSS/) will be a freely distributable set of analysis programs, still under development at this writing. It will run on UNIX server computers, with a command-line interface. EMBOSS will include various sequence analysis topics, and will include a major effort to provide easy integration of other public domain packages. Analyses include rapid database searching with sequence patterns, and for sequence overlaps, simple and species-specific repeat identification, nucleotide sequence pattern analysis, codon usage analysis for small genomes, gene identification tools for genomic sequencing, rapid identification of sequence patterns in large scale sequence sets, protein motif identification, and presentation tools for publication.

These could be the basic analysis engines for sequence analysis, and some client program with a good user interface, perhaps like SeqPup, Java applets, or web forms, can be the program you use to run the analyses.

2. Free software highlights

2.1 Clustal sequence alignment

Clustal provides automatic multiple sequence alignment. The current version is called Clustal W, and is available for MacOS, Wintel, UNIX, and VMS computers. The simultaneous alignment of many nucleotide or amino acid sequences is now an essential tool in molecular biology. Multiple alignments are used to find diagnostic patterns to characterize protein families; to detect or demonstrate homology between new sequences and existing families of sequences; to help predict the secondary and tertiary structures of new sequences; to suggest oligonucleotide primers for PCR; as an essential prelude to molecular evolutionary analysis. The Clustal program fits this need very well. It is available at ftp://ftp-igbmc.u-strasbg.fr/pub/ClustalW and at EBI and IUBio archives. There is a companion program ClustalX which provides a graphic interface to Clustal, and Clustal can be used from other sequence editors such as SeqPup.

2.2 Entrez to search genome data

The Entrez program is used for keyword searches of gene sequence data and Medline literature. It has been written by the programming staff at the National Center for Biotechnology Information (NCBI). It can be obtained from http or ftp://ncbi.nlm.nih.gov/. Entrez runs on a variety of computer systems. One big advantage of Entrez is the inclusion of a subset of MEDLINE, which covers the abstracts of entries submitted to the sequence databases. The WWW service of NCBI also offers an Entrez type of capability through your web browser. The program source for Entrez developed at NCBI has been instrumental in providing a software framework for other biosciences applications, including a version of SeqPup and Clustal-X.

2.3 NIH Image for image analysis

A very useful Macintosh program for general image analysis is NIH Image, written by Wayne Rasband. Image can be used to measure the area, average density, center of gravity, and angle of orientation of a user defined region of interest. It also performs automated particle analysis and can be used to measure path lengths and angles. Measurement results can be printed, exported to text files, or copied to the clipboard. Results can be calibrated to provide real world values. Find Image at ftp://zippy.nimh.nih.gov/pub/nih-image/, or http://rsb.info.nih.gov/nih-image/. There is now a version for MS Windows, from http://www.scioncorp.com/ .

2.4 PHYLIP for phylogeny analyses

The widely used Phylogeny Inference Package, PHYLIP, from Joseph Felsenstein, is a package of programs for inferring phylogenies (evolutionary trees), and written to work on as many different of computer systems as possible. It includes analyses of DNA and protein sequences, restriction sites, distance matrices and gene frequencies, quantitative and discrete characters, and plotting of evolutionary trees. Algorithms used include parsimony, maximum likelihood, neighbor joining and several others. Many options for precise control of the analyses are available. The home for PHYLIP is at http or ftp://evolution.genetics.washington.edu/.

2.5 RasMol for molecular modeling

RasMol is a widely used, free molecular graphics program for the visualization of proteins, nucleic acids and small molecules. The program is aimed at display, teaching and generation of publication quality images. RasMol runs on all common computer systems. The program reads in molecule co-ordinates and interactively displays the molecule in a variety of color schemes and molecule representations, including depth-cued wireframes, space-filling spheres, ball and stick, solid and strand biomolecular ribbons, atom labels and dot surfaces. The home for RasMol is ftp://ftp.dcs.ed.ac.uk/pub/rasmol/

2.6 SeqPup for sequence editing

SeqPup, and its predecessor SeqApp, are biological sequence editor and analysis programs. They includes links to network services and external analysis programs. SeqPup is usable on common computer systems, using the new Java language.

Features include multiple sequence alignment and single sequence editing, read and write several sequence file formats, pretty print of alignments and sequences with boxed and shaded regions, sequence feature editing, manipulation and marking in prints, consensus, reverse-complement, distance/similarity, translate DNA to/from protein. Print file formats include PICT, Postscript and GIF.

User-definable links to external analysis programs, including ClustalW multiple alignment, CAP contig assembly, tacg restriction maps, fastDNAml phylogenetic analysis are included, and others can be added by you. One can use these running on your own computer or on an Internet server computer, using a new CORBA protocol (www.corba.org). Internet sequence analysis services include fetching sequences using SRS keyword search, and performing NCBI-BLAST similarity searches.

The home for SeqPup is http://iubio.bio.indiana.edu/soft/molbio/seqpup/. Note that this application is a work in progress; it has bugs. SeqApp is the Macintosh-only predecessor to SeqPup. Many folks find this currently a more useful program than SeqPup. It is faster, but lacks newer features of SeqPup.

3. Software use issues

3.1 Copyrighted versus public domain

Most free software is copyrighted by the author or sponsor, who retain all rights. They specifically grant you a right to use this software freely, perhaps only for non-commercial uses. Use of copyrighted software in commercial packages or other uses that make money require consent from the author. Many of the free software programs come with source code, so you can modify and extend it. This is a great boon to let sophisticated users do a needed analysis, but keep in mind use of such in a commercial product isn't allowed. If the author explicitly places his work in the public domain, s/he retains no control, and it can be used in commercial applications.

3.2 Citing software publications

Publicly available software is a publication, and free software that you use should be treated with consideration that you give other publications used in your research. While some free software has a companion paper publication to cite, some does not. It is usual practice to cite a software publication with its Internet URL in place of the journal/volume portion, e.g.,

Felsenstein, J. 1993. PHYLIP (Phylogeny Inference Package) version 3.5c. Distributed by the author at ftp://evolution.genetics.washington.edu/. Department of Genetics, University of Washington, Seattle.

Gilbert, D.G., 1996. SeqPup, biosequence editor & analysis platform, version 0.6. Bionet.Software, July 1996. <news://4rb7hr$6rc@usenet.ucs.indiana.edu> See also ftp://iubio.bio.indiana.edu /molbio/seqpup/

Some of these programs have been available at the same location for 10 years or more, so there isn't a general problem of impermanence with Internet locators.
