[Biojava-l] Parsing location from gbk files

[Schreiber, Mark]

Hi -
 
This is a recurring problem as more files are being deposited that contain only references to other contigs but contain annotation and features.
 
A model where a DummySequence of appropriate length is instantiated if the contig files are not available may be useful. Possibley a GBS parser would be useful? Has anyone hacked out something like this?

	Hi,
	
	I am using biojava to extract mRNA, CDS and gene boundaries from genbank annotation files (e.g., "hs_chr19.gbs" from ftp://ftp.ncbi.nih.gov/genomes/H_sapiens/CHR_19/).
	I've just switched from the biojava 1.22 to latest 1.3 release (biojava-1.30-jdk14.jar and bytecode-0.92.jar)
	and I get lots of exception (see below, the peace of code generating this follows as well). Don't known if it's important but ".gbs" files do not hold the contig sequences but only annotations.
	
	Nota: I am using the jdk 1.4.1.
	
	Thanks for your help.
