The flower package

[Tags:gpl, program]

flower - FLOWgram ExtractoR tools

The flower executable reads files in SFF-format and produces various output, including sequences with quality, or flowgram data in tabular format. By default, it outputs a textual representation of the data in the SFF-file, much like sffinfo from Roche does.

The fselect executable extracts reads from SFF-files, generating a new SFF-file with a subset of the reads based on various criteria.

Sometimes SFF files will appear to be corrupted, with all-zero blocks in the file. The frecover program ignores these and tries to resync with the file after an invalid region. This was likely a one-time bug in the 454 software, so this program is probably not so useful any more.
