kalign - performs multiple alignment of biological sequences.
kalign [infile.fasta] [outfile.fasta] [Options]
kalign [-i infile.fasta] [-o outfile.fasta] [Options]
kalign [< infile.fasta] [> outfile.fasta] [Options]
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.
-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.
Selects feature mode and specifies which features are to be used:
e.g. all, maxplp, STRUCT, PFAM-A?
Score for aligning same features.
Penalty for aligning different features.
-d -distance <wu, pair>
-b -tree -guide-tree <nj, upgma>
Guide tree method.
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.
Increases gap penalties depending on the number of existing gaps.
-f -format <fasta, msf, aln, clu, macsim>
The output format.
Print nothing to STDERR. Read nothing from STDIN.
