[Biojava-l] I don't know why I can't let my program read SCF files.

[Shin Negishi]

Dear Sir,

  My name is Shin Negishi. I am a graduate student of Tokyo Institute of
Technology.
I belong to Dr.Gondo's laboratory. Dr. Gondo is the leader of Population and
Quantitative
genomics team in RIKEN GSC and is also a visiting professor of the graduate
school.
My research field is SNP discovery. I would like to make a software for SNP
discovery.
So I must make programs which can read files in various format. Now, I try
to let my
program read SCF files. But, I can't do it. Please help me! I put the part
of my program
and error massages below:


import java.io.*;
import org.biojava.bio.*;
import org.biojava.bio.chromatogram.*;
import org.biojava.bio.program.scf.SCF;
import org.biojava.bio.seq.*;

public class Test {
  public static void main(String[] args)
  throws Exception {
    File traceFile = new File(args[0]);

    //read the trace
    SCF traces = SCF.create(traceFile);

    int[] t = traces.getTrace(NucleotideTools.t());
    int[] g = traces.getTrace(NucleotideTools.g());
    int[] c = traces.getTrace(NucleotideTools.c());
    int[] a = traces.getTrace(NucleotideTools.a());
  }
}
