Example 6 with Histogram

use of ubic.basecode.math.distribution.Histogram in project Gemma by PavlidisLab.

the class DifferentialExpressionResultDaoImpl method loadPvalueDistribution.

@Override
public Histogram loadPvalueDistribution(Long resultSetId) {
    List<?> pvds = this.getHibernateTemplate().findByNamedParam("select rs.pvalueDistribution from ExpressionAnalysisResultSet rs where rs.id=:rsid ", "rsid", resultSetId);
    if (pvds.isEmpty()) {
        return null;
    }
    assert pvds.size() == 1;
    PvalueDistribution pvd = (PvalueDistribution) pvds.get(0);
    ByteArrayConverter bac = new ByteArrayConverter();
    double[] counts = bac.byteArrayToDoubles(pvd.getBinCounts());
    Integer numBins = pvd.getNumBins();
    assert numBins == counts.length;
    Histogram hist = new Histogram(resultSetId.toString(), numBins, 0.0, 1.0);
    for (int i = 0; i < numBins; i++) {
        hist.fill(i, (int) counts[i]);
    }
    return hist;
