missing userfields options #548
Description
As a follow-up on issue #545, here is a list of --userfields options available in usearch (see userfields), but not in vsearch.
Starting with the most important, in my opinion:
diffs Number of differences (gaps + mismatches).
mid Fraction of letter pairs that match.
qseq Full-length query sequence.
tseq Full-length target sequence.
qrowdots Aligned query segment with gaps and dots for matched positions.
trowdots Aligned target segment with gaps and dots for matched positions.
These other options are less important, or are specific to commands not yet available in vsearch:
abskew Abundance skew.
clusternr Cluster number.
qlor 0-based query start coordinate.
qhir 0-based query end coordinate.
tlor 0-based target start coordinate.
thir 0-based target end coordinate.
orflo Start coordinate of query ORF in nt sequence.
orfhi End coordinate of query ORF in nt sequence.
orfframe Frame of query ORF.
