This is the BETA distribution of the NCSA ContigAsm program. It reads the output of the NCSA GelReader (gel mobilities) and assembles contigs from it. It considers error bars when searching for matches and allows the user to enter a value to be used as a certainty metric for the overlap searches. This is a new pre-beta distribution, version alpha 1. Release data January 9, 1990. The distribution file is in a binhexed, stuffed archive. You will need the programs BinHex and StuffIt to decode the archive. It contains the rough documentation, the application and a set of sample gelreader output files. Tom Redman
