Problems 1, 2, & 3

Creating a gene

genes[0] = new Feature(ORG, GENE, "xfile", false, false, now, now);
 
genes[0].setSeqLen(1029);
sequenceDao.persist(genes[0]);
 
FeatureLoc loc = new FeatureLoc(SOURCE_FEATURE, genes[0], 13691, false, 14720, false, (short)1, 0, 0 ,0);
 
sequenceDao.persist(loc);
 
addFeatureProp(genes[0], "description", "A test gene for GMOD meeting");
 
addSynonymsToFeature(genes[0], "mulder", "scully");
 
createExon("exon1", genes[0], 13691, 13767, now, 0);
 
createExon("exon2", genes[0], 14687, 14720, now, 1);

Retrieve a gene

Feature f = sequenceDao.getFeatureByUniqueName("xfile");
displayGene(f);

Update a gene

genes[0].setUniqueName("x-file");
 
sequenceDao.merge(genes[0]);
private Feature createExon(String name, Feature gene, int min, int max, Timestamp now, int rank) {
 
        Feature exon = new Feature(ORG, EXON, name, false, false, now, now);
        exon.setSeqLen(max-min);
        sequenceDao.persist(exon);
 
        FeatureLoc loc = new FeatureLoc(SOURCE_FEATURE, exon, min, false, max, false,
                                      (short)1, 0, 0 ,0);
        sequenceDao.persist(loc);
 
        return exon;
 
}
