maffilter - 1.3.1+dfsg-6+b1 main

MafFilter applies a series of "filters" to a MAF file, in order to
clean it, extract data and computer statistics while keeping track of
the associated meta-data such as genome coordinates and quality scores.
.
* It can process the alignment to remove low-quality / ambiguous /
masked regions.
* It can export data into a single or multiple alignment file in
format such as Fasta or Clustal.
* It can read annotation data in GFF or GTF format, and extract the
corresponding alignment.
* It can perform sliding windows calculations.
* It can reconstruct phylogeny/genealogy along the genome alignment.
* It can compute population genetics statistics, such as site
frequency spectrum, number of fixed/polymorphic sites, etc.
