Usage example:

// dtaSelect File object
File dtaSelectFile = ...

// Create the parser
DTASelectParser parser = new DTASelectParser(dtaSelectFile.toURL());

// get number of proteins
final int numProteins = parser.getDTASelectProteins().size();

// get number of PSMs
final int numPSMs = parser.getDTASelectPSMsByPSMID().size();

// get number of peptides
final int numPeptides = parser.getDTASelectPSMsBySequence().size();

// get number of protein groups
final int numProteinGroups = parser.getProteinGroups().size();

// get a particular protein
final DTASelectProtein dtaSelectProtein = parser.getDTASelectProteins().get("P10120");

// print accession
System.out.println(dtaSelectProtein.getLocus());

// get PSMs associated to that protein and print the number
final List<DTASelectPSM> psMs = dtaSelectProtein.getPSMs();
System.out.println(psMs.size() + " PSMS");

// iterate over the psms
for (DTASelectPSM dtaSelectPSM : psMs) {

  // print the psm ID and the DeltaCn and Xcorr scores
	System.out.println(dtaSelectPSM.getPsmIdentifier() + " " + dtaSelectPSM.getDeltacn() + " " + dtaSelectPSM.getXcorr());
	
  // print the peptide sequence with modifications (if available), without modifications and 
	System.out.println(dtaSelectPSM.getSequence().getRawSequence() + " "	+ dtaSelectPSM.getSequence().getSequence());
	
}
