MAF (Multiple Alignment Format)

The Multiple Alignment Format stores a series of multiple alignments.   See the UCSC web site for more details.  The extension must be ".maf".  

NOTE: .maf files must be indexed, and in plain text (not gzipped) with a .maf extension.  IGV will create an index for the file on first use, which will result in a delay in loading.   Do not close IGV while indexing is in progress.
