Concatenate several alignments (with the same sequence names) end-to-end.

NAME

alignment-cat - Concatenate several alignments (with the same sequence names) end-to-end.

SYNOPSIS

alignment-cat file1 [file2 ...]

DESCRIPTION

Concatenate several alignments (with the same sequence names) end-to-end.

ALL OPTIONS:

-h, –help

Produce help message

–output arg (=fasta)

Which output format: fasta or phylip?

-c arg, –columns arg

Ranges of columns to keep, like: 1-10,30-

-t arg, –taxa arg

Taxa to keep, comma-separated

-p, –pad

Add gaps to make sequence lengths identical

-r, –reverse

Reverse the sequences

-e, –erase-empty-columns

Remove columns with no characters (all gaps).

–missing arg (=-?)

What letters are not characters (e.g. gaps)?

–strip-gaps

Remove all non-character letters from sequences.

–reorder-by-tree arg

Reorder the sequences given a tree

–use-root

use the root specified in the tree file to reorder

–reorder-by-alignment arg

Reorder the sequences following an alignment

–align-by-amino arg

Arrange nucleotides into codon alignment

EXAMPLES:

To select columns from an alignment:

% alignment-cat -c1-10,50-100,600- filename.fasta > result.fasta
% alignment-cat -c5-250/3 filename.fasta > first_codon_position.fasta
% alignment-cat -c6-250/3 filename.fasta > second_codon_position.fasta

To concatenate two or more alignments:

% alignment-cat filename1.fasta filename2.fasta > all.fasta
