Not sure which forum this should be in, but I wrote this parser a while back to go from genscan, geneid, and fgenesh to the bio::graphics format used in the Wormbase’s Sequence Feature Renderer. I thought it might be useful to someone.
It is linked in Rearch->Other on http://www.nd.edu/~jspies/. The direct link is http://www.nd.edu/~jspies/index.php?page=tobiographics, but this could change.
