BioMAJ downloads remote data banks, checks their status and applies
transformation workflows, with consistent state, to provide ready-to-use
data for biologists and bioinformaticians. For example, it can transform
original FASTA files into BLAST indexes. It is very flexible and its
post-processing facilities can be extended very easily.
Biomaj3 is a complete rewrite of the original biomaj package, in python, and using mongodb instead of mysql. It also provides bug fixes and new features.
