NAME

kalign - performs multiple alignment of biological sequences.

SYNOPSIS

kalign [infile.fasta] [outfile.fasta] [Options]
kalign [-i infile.fasta] [-o outfile.fasta] [Options]
kalign [< infile.fasta] [> outfile.fasta] [Options]

DESCRIPTION

Kalign

is a command line tool to perform multiple alignment of biological sequences. It employs the Muth?Manber string-matching algorithm, to improve both the accuracy and speed of the alignment. It uses global, progressive alignment approach, enriched by employing an approximate string-matching algorithm to calculate sequence distances and by incorporating local matches into the otherwise global alignment.

OPTIONS

-s -gpo -gapopen -gap_open x

Gap open penalty .

-e -gpe -gap_ext -gapextension x

Gap extension penalty.

-t -tgpe -terminal_gap_extension_penalty x

Terminal gap penalties.

-m -bonus -matrix_bonus x

A constant added to the substitution matrix.

-c -sort <input, tree, gaps.>

The order in which the sequences appear in the output alignment.

-g -feature

Selects feature mode and specifies which features are to be used: e.g. all, maxplp, STRUCT, PFAM-A?

-same_feature_score

Score for aligning same features.

-diff_feature_score

Penalty for aligning different features.

-d -distance <wu, pair>

Distance method

-b -tree -guide-tree <nj, upgma>

Guide tree method.

-z -zcutoff

Parameter used in the wu-manber based distance calculation.

-i -in -input

Name of the input file.

-o -out -output

Name of the output file.

-a -gap_inc

Increases gap penalties depending on the number of existing gaps.

-f -format <fasta, msf, aln, clu, macsim>

The output format.

-q -quiet

Print nothing to STDERR. Read nothing from STDIN.
