DESCRIPTION

       showalign is a command line program from EMBOSS (“the European Molecular Biology Open
       Software Suite”). It is part of the "Alignment:Multiple,Data retrieval:Sequence data"
       command group(s).

OPTIONS

   Input section
       -sequence seqset
           The sequence alignment to be displayed.

       -matrix matrix
           This is the scoring matrix file used when comparing sequences. By default it is the
           file 'EBLOSUM62' (for proteins) or the file 'EDNAFULL' (for nucleic sequences). These
           files are found in the 'data' directory of the EMBOSS installation.

   Additional section
       -refseq string
           If you give the number in the alignment or the name of a sequence, it will be taken to
           be the reference sequence. The reference sequence is always shown in full and is the
           one against which all the other sequences are compared. If this is set to 0 then the
           consensus sequence will be used as the reference sequence. By default the consensus
           sequence is used as the reference sequence.

       -bottom boolean
           If this is true then the reference sequence is displayed at the bottom of the
           alignment instead of the top. Default value: Y

       -show list
           Default value: N

       -order list
           Default value: I

       -similarcase boolean
           If this is set True, then when -show is set to 'Similarities' or 'Non-identities' and
           a residue is similar but not identical to the reference sequence residue, it will be
           changed to lower-case. If -show is set to 'All' then non-identical, non-similar
           residues will be changed to lower-case. If this is False then no change to the case of
           the residues is made on the basis of their similarity to the reference sequence.
           Default value: Y

       -consensus boolean
           If this is true then the consensus line is displayed. Default value: Y

   Advanced section
       -uppercase range
           Regions to put in uppercase. If this is left blank, then the sequence case is left
           alone. A set of regions is specified by a set of pairs of positions. The positions are
           integers. They are separated by any non-digit, non-alpha character. Examples of region
           specifications are: 24-45, 56-78 1:45, 67=99;765..888 1,5,8,10,23,45,57,99

       -number boolean
           If this option is true then a line giving the positions in the alignment is displayed
           every 10 characters above the alignment. Default value: Y

       -ruler boolean
           If this option is true then a ruler line marking every 5th and 10th character in the
           alignment is displayed. Default value: Y

       -width integer
           Default value: 60

       -margin integer
           This sets the length of the left-hand margin for sequence names. If the margin is set
           at 0 then no margin and no names are displayed. If the margin is set to a value that
           is less than the length of a sequence name then the sequence name is displayed
           truncated to the length of the margin. If the margin is set to -1 then the minimum
           margin width that will allow all the sequence names to be displayed in full plus a
           space at the end of the name will automatically be selected. Default value: -1

       -html boolean
           Default value: N

       -highlight range
           Regions to colour if formatting for HTML. If this is left blank, then the sequence is
           left alone. A set of regions is specified by a set of pairs of positions. The
           positions are integers. They are followed by any valid HTML font colour. Examples of
           region specifications are: 24-45 blue 56-78 orange 1-100 green 120-156 red A file of
           ranges to colour (one range per line) can be specified as '@filename'.

       -plurality float
           Set a cut-off for the % of positive scoring matches below which there is no consensus.
           The default plurality is taken as 50% of the total weight of all the sequences in the
           alignment. Default value: 50.0

       -setcase float
           Sets the threshold for the scores of the positive matches above which the consensus is
           in upper-case and below which the consensus is in lower-case. By default this is set
           to be half of the (weight-adjusted) number of sequences in the alignment. Default
           value: @( $(sequence.totweight) / 2)

       -identity float
           Provides the facility of setting the required number of identities at a position for
           it to give a consensus. Therefore, if this is set to 100% only columns of identities
           contribute to the consensus. Default value: 0.0

       -gaps boolean
           If this option is true then gap characters can appear in the consensus. The
           alternative is 'N' for nucleotide, or 'X' for protein Default value: Y

   Output section
       -outfile outfile
