David -
you can get control of how to write the GenBank line by using the "id generation function" hook inside of the bioperl parser. You need to pass in a function that generates the correct string from the bioperl sequence object. This gives complete control of the LOCUS line. Ensembl has to output strictly correct EMBL and GenBank so all the necessary hooks are there for this. Probably in general we should output with the DATE line by default. The only problem is that there is an obvious thing to use when we are coming from a format that doesn't have a date. I've put this in as a bug report and hope to fix it for 1.0 BTW - Andrew's suggestion of writing out the header portion is almost certainly a bad idea. A format definition is a mixture of the precise definition and its common usage. Also the old adage rings true "be permissive in what you accept but strict in what you output". e. _______________________________________________ Biojava-l mailing list - [EMAIL PROTECTED] http://biojava.org/mailman/listinfo/biojava-l
