pxclsq(1)

NAME

pxclsq - clean positions or taxa with too much ambiguous data

SYNOPSIS

pxclsq [OPTIONS]...

DESCRIPTION

Clean alignments by removing positions/taxa with too much ambiguous data. This will take fasta, fastq, phylip, and nexus formats from a file or STDIN. Results are written in fasta format.

OPTIONS

-s, --seqf=FILE: input sequence file, STDIN otherwise

-p, --prop=DOUBLE: proportion required to be present, default=0.5

-e, --empty: remove columns that are completely empty (- or ?)

-m, --min=INT: the minimum number of good characters required per site - a min of 1 is equivalent to -e above

-t, --taxa: consider missing data per taxon (default: per site)

-c, --codon: examine sequences by codon rather than site - requires all sequences be in frame and of correct length

-i, --info: report counts of missing data and exit - combine with -t to get report by taxon (rather than site) - combine with -c to use codons as units

-v, --verbose: more verbose output (i.e. if entire seqs are removed)

-o, --outf=FILE: output fasta file, STOUT otherwise

-h, --help: display this help and exit

-V, --version: display version and exit

-C, --citation: display phyx citation and exit
