The problem is that ABI software (like all software) is often deficient in several ways.
The initial version of the Inherit Assembly program, for example, was almost unusable.
Although the assembled sequences were very good (among the best of 10 different assembly
programs I've examined), the editor was hopelessly cumbersum -- it took almost 13 minutes
find and fix 8 errors in one assembly, as opposed to 45 seconds with Sequencher. Their
more recent version, AutoAssembler, has a vastly improved editor, which is similar in
design to that of Sequencher. Now, there is the *perception* that ABI is modifying, and
de facto encripting, its code so as to break other programs. This strikes people as
unfair and potentially detrimental to their science. Compression is obviously useful,
but ABI should certainly tell people which compression algorithm is being used.

Certainly no one should question ABIs right to modify their file formats for the
purpose of adding value to their product. I have deep problems if the purpose is to
gain a monopolistic lock on the market. ABI can easily release the file formats with
a big disclaimer noting they can be changed at any time without notice. The
compression method should be disclosed or the ability to uncompress one's data should
be added to the software.
As a scientist, I demand to have access to my raw data. I would be very hesitant
to buy an insturment that outputs heavily processed data (as the ABI trace files are)
without being able to access my raw data (the chromatogram profiles are much different
from the final trace profiles).
