NAME

       Bio::AlignIO::metafasta - Metafasta MSA Sequence input/output stream

SYNOPSIS

       Do not use this module directly.  Use it via the Bio::AlignIO class.

DESCRIPTION

       This object can transform Bio::SimpleAlign objects to and from metafasta flat file databases.

       The format of a metafasta file is

         >test/1-25
         ABCDEFHIJKLMNOPQRSTUVWXYZ
         &charge
         NBNAANCNJCNNNONNCNNUNNXNZ
         &chemical
         LBSAARCLJCLSMOIMCHHULRXRZ

       where the sequence block is followed by one or several meta blocks.  Each meta block starts with the
       ampersand character '&' in the first column and is immediately followed by the name of the meta data
       which continues until the new line. The meta data follows it. All characters, except new line, are
       important in meta data.
