dear, there seems to be some problem with the bogas_Bathy DB => some genes are assigned to contigs that are not present in the contigs table (nor in the blastDBs)! possible typo : chrom017-28 in stead of chrom028-17? best, L. PS. @ developers: can we not add these constraints/links in the DB (all contig_id from gene table should be in contigs table). -- ============================================================== Lieven Sterck, PhD Tel:+32 (0)9 3313821 Fax:+32 (0)9 3313809 VIB Department of Plant Systems Biology, UGent Bioinformatics and Evolutionary Genomics Division Technologiepark 927, B-9052 Gent, Belgium Email: lieven.sterck@psb.vib-ugent.be Website: http://bioinformatics.psb.ugent.be ============================================================== "You tried your best and you failed miserably.
