| File | Multiple sequence alignment file (ASCII text file). Enter a file name,
a path and file name, or a URL pointing to a file. File can
also be a MATLAB® character array that contains the text of a multiple
sequence alignment file. You can read common multiple alignment file types, such as ClustalW (.aln) and GCG (.msf). |
| IgnoreGapsValue | Property to control removing gap symbols. |
S = multialignread(File) reads a multiple sequence alignment file. The file contains multiple sequence lines that start with a sequence header followed by an optional number (not used by multialignread) and a section of the sequence. The multiple sequences are broken into blocks with the same number of blocks for every sequence. (For an example, type open aagag.aln.) The output S is a structure array where S.Header contains the header information and S.Sequence contains the amino acid or nucleotide sequences.
[Headers, Sequences] = multialignread(File) reads the file into separate variables Headers and Sequences.
multialignread(..., 'PropertyName', PropertyValue,...) defines optional properties using property name/value pairs.
multialignread(..., 'IgnoreGaps', IgnoreGapsValue), when IgnoreGapsValue is true, removes any gap symbol ('-' or '.') from the sequences. Default is false.
Read a multiple sequence alignment of the gag polyprotein for several HIV strains.
