       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.

       -g -feature
           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>
           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.
