[Biojava-l] Parsing SwissProt flat file through BioJava

[Roy Park]

The following code should give you some ideas:

SequenceIterator seqIter = SeqIOTools.readSwissprot(br);
while (seqIter.hasNext()) {
	Sequence thisSeq = seqIter.nextSequence();
	Annotation thisAnnot = thisSeq.getAnnotation();
	// Get species info..
	String species = thisAnnot.getProperty("OS");
	.
	.
}

etc.

The Annotation.getProperty() call may end up returning an ArrayList of
Strings instead (of a String object), if there are multiple XX entries. i.e.
it could very well be:

	String species = thisAnnot.getProperty("XXXXXX");

for SOME of the properties.  Personally, I handle this by writing a utility
static method that can take either an ArrayList (of String) object or a
String object, and returns a String object.

Hello,

I am Rahul Deshpande. I work for a bio informatics company. Recently I came
across biojava.
I have a question about biojava.

How can we read the SwissProt flat files using biojava? The closest we could
come was org.biojava.bio.seq.io.EmblLikeFormat class which has methods to
return the two letter code and the remaining data in the line. Can we
retrieve the data for each protein in the SwissProt flat file instead of
reading each line by each line? Are there any methods like that?
