What it does
Fasta entries are sorted by decreasing abundance (−−sortbysize) or sequence length (−−sort- bylength). To obtain a stable sorting order, ties are sorted by decreasing abundance and label increasing alpha-numerical order (−−sortbylength), or just by label increasing alpha-numerical order (−−sortbysize). Label sorting assumes that all sequences have unique labels. The same applies to the automatic sorting performed during chimera checking (−−uchime_denovo), derepli- cation (−−derep_fulllength), and clustering (−−cluster_fast and −−cluster_size).
--maxsize INT | maximum abundance for sortbysize |
--minsize INT | minimum abundance for sortbysize |
--output FILENAME | |
output FASTA file | |
--relabel STRING | |
relabel with this prefix string after sorting | |
--sizeout | add abundance annotation to output |
--sortbylength FILENAME | |
sort sequences by length in given FASTA file | |
--sortbysize FILENAME | |
abundance sort sequences in given FASTA file | |
--topn INT | output just top n seqs after sorting |
