Alignment files are included in two gzipped (compressed) text formats; many browsers will automatically uncompress these files. ALN, AE2 (Macke) format; GB, GenBank format. In addition to the sequences, the alignments also contain phylogenetic group dividers (using NCBI's taxomomy information) and several informational sequences which are not included in the counts below.
