Bio::Variation::IO::flat - flat file sequence variation input/output stream


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


This object can transform Bio::Variation::SeqDiff objects to and from flat file databases. The format used is EMBL like extension of what is used by the "EBI Mutation Checker" at http://www.ebi.ac.uk/cgi-bin/mutations/check.cgi and will eventually replace it.

More information of the attributes and values use can be found at http://www.ebi.ac.uk/mutations/recommendations/.
