**What it does**

By default it divides a FASTA, FASTQ or Standard Flowgram Format (SFF) file in
two, those sequences with or without an ID present in the tabular file column(s)
specified. You can opt to have a single output file of just the matching records,
or just the non-matching ones.

Note that the order of sequences in the original sequence file is preserved, as
is any Roche XML Manifest in an SFF file. Also, if any sequences share an
identifier (which would be very unusual in SFF files), duplicates are not removed.

**Example Usage**

You may have performed some kind of contamination search, for example running
BLASTN against a database of cloning vectors or bacteria, giving you a tabular
file containing read identifiers. You could use this tool to extract only the
reads without BLAST matches (i.e. those which do not match your contaminant
database).

You may have a file of FASTA sequences which has been run some some analysis
tool giving tabular output, which has then been filtered on some criteria.
You can then use this tool to divide the original FASTA file into those entries
matching or not matching your criteria (those with or without their identifier
in the filtered tabular file).
