Hi, I just stumbled over my sequence IDs getting trimmed to 10 characters when writing with Bio::SeqIO::embl. line 453: $temp_line = sprintf("%-11.10sstandard; $mol; $div; %d BP.", $seq->id(), $len); Is there any reason for the trimming? I can´t find any hints for that in the EMBL manual... Thanks in advance, Daniel:)
