BioJava using SEED Web Services

For a few days I’ve been testing the waters of the SEED Web Services methods and trying to get a feel for the different ways they could be implemented, and at the same time was doing the same for BioJava. After aquiring enough knowledge of sequences, pegs, and other things I was finally able to get them to use each other’s methods to display and store information for anyone to use. Here is a really simple example where the Web Services obtains a genome ID, “83333.1”, and a region on the chromosome, “NC_000913_1303788_1304792”, and then returns a sequence. Then, BioJava uses its createDNA() method to convert the sequence into an object it can manipulate. The code then prints out different properties held by the sequence.

import gov.anl.mcs.bioseed.SeedWebServices.SeedWebServicesHandler;
import gov.anl.mcs.bioseed.SeedWebServices.SeedWebServicesHandlerProxy;

import java.rmi.RemoteException;


public class WebAccessTester2 {

public static void main(String[] args) {

SeedWebServicesHandler service = new SeedWebServicesHandlerProxy();

String tmp[];
SymbolList seq;

try {

tmp = service.dna_sequence("83333.1", "NC_000913_1303788_1304792", "NC_000913_1303788_1304792");
seq = DNATools.createDNA(tmp[0]);

System.out.println("Alphabet = " + seq.getAlphabet().getName());
System.out.println("Length = " + seq.length());
System.out.println("First symbol = " + seq.symbolAt(1).getName());

} catch (RemoteException e) {
// Do some error handling for remote access.
} catch (IllegalSymbolException e) {
// Do some more error handling.

Here is the output:

Alphabet = DNA
Length = 2010
First symbol = adenine

Note: The last string does not cut off with ellipses. It was too long for my purposes here Smile
