Welcome then to the Biojava community! I think you have a corrupt Biojava library (biojava.jar) or maybe there are resources missing in the classpath. What you should do is:
- Download the latest binary snapshot of Biojava from http://www.derkholm.net/autobuild/binaries/ - Check that you put all the libraries needed in the classpath: java -cp /path/to/one/jar:/path/to/another/jar ReadGB input_file (also you can have those jars in the CLASSPATH environment variable. You should put the jars explained at http://biojava.org/download14.html After reading the file successfully you will get a Sequence object... you can try to just print the sequence name (in this case the accession number) just using: String seqName = seq.getName(); System.out.println(seqName); and there are many other (and sophisticated) possibilities, of course!
