The AB1 file format specs are ABI "secrets" :-( That said many people have
reverse engineered them. Clark Tibbets wrote something about this at some
stage - try searching with Google.
We also provide a free C library for reading AB1, ALF, SCF, CTF and ZTR trace
files, as well as writing SCF, CTF and ZTR. The C code itself serves, to some
extent, as documentation for the file formats. The SCF and ZTR formats are
described on our web site. ZTR is the latest format and if you're interested
in saving disk space is probably the best at the moment (me biased? surely not
The io_lib C code can be downloaded from:
