NAME

  Bio::GeneMerge - GeneMerge based GO analyzer

VERSION

Version 0.01

SYNOPSIS

  #!/usr/bin/perl -w

  use Bio::GeneMerge;

  $test = Bio::GeneMerge->new();

  if ($test->getDescFile("GO/use/GO.BP.use") < 0){
     print"Desc error\n"
  }

  if ($test->getAssocFile("GO/assoc/A_thaliana.converted.BP") < 0){
     print"Assoc error\n"
  }

  if ($test->getPopFile("GO/pop.500") < 0){
     print"Pop error\n"
  }

  if ($test->getStudyFile("GO/study.500/combined1314.list") < 0){
     print"Study error\n"
  }

  $results = $test->getResults();

  foreach $res (@{$results}) {
     print $$res{'GOterm'}," ",$$res{'RawEs'},"\n";
  }

DESCRIPTION

  This is a module based on GeneMerge v1.2. Original program
  created by Cristian I. Castillo-Davis (castill0@stat.umd.edu)

  Post-genomic analysis, data mining, and hypotesis testing.
  The original program is not too good for large scale analysis, 
  because the design use a lot of I/O process. This version is
  take the whole process into the memory.

  This is the constructor.

getAssocFile

  The method load the GO association file and store it in memory.

getPopFile

   The method load the Population file and store it in memory.

popFreq

   The method calculate the population frequency.
   Do not use it directly.

getDescFile
