I've CC'd the common OpenBio mailing list as this is probably of
interest beyond just BioJava.

Based on code from Jose Blanca (author of sff_extract), I
implemented support for the SFF (Roche 454) sequencing reads
for Biopython last year on a branch that I hope to merge into our
next release, currently here:


In addition to the Roche Manuals (which may not be that easy to
get a copy of), the SFF format is described on this NCBI webpage:


I'm happy to answer questions on how the file format works
(including the undocumented index block which I had to reverse


P.S. Just to clarify (from the old BioJava thread), the SFF file just
holds the raw reads - it is an input file for doing an assembly or
