New Release with 1109 genomes is here

The May 2011 release of OMA consists of 1109 genomes is now online. The interruption of the OMA Browser was only for a short time, now everything should work well.

The current release contains many new and updated plant (Cassava, Rice, Ostreococcus) and insect genomes (Louse, Mosquito, Aphid, several Flies), the Giant Panda and various new Archaea and Bacterias.

From this release on, we also provide cross-references to Refseq and EntrezGene identifiers for protein sequences which are identical.

Coming up: new release with 1109 genomes

Good news! We have finally finished the computation of a new data set with 1109 genomes.

The new data set will be available in the OMA Browser within the next two days. This can cause short interruption of the web server. Sorry for any inconveniences. The data of the current release will be available in the OMA Browser Archive.

New Release (Nov 2010)

We're pleased to announce the 11th release (Nov 2010) of OMA.

For this release, we added a new grouping strategy: Apart from the OMA groups, we now also provide hierarchical groups containing orthologs and inparalogs within a user selectable taxonomic range.

We have also added a new consistency criterion for our pairwise ortholog predictions, which assures that the predictions between a pair of genomes are biological consistent. Due to this new criterion, we corrected a small fraction of our predictions.

New release (May 2010) is here

The May 2010 release of OMA with 1000 genomes is now online. The interruption of the OMA Browser was only for a short time, now everything should work well.
The data of the previous releases is still available for download.

IDs and Sequences of TETNG (Tetraodon nigroviridis) fixed

Dear users,

we could fix the problems with the Tetraodon nigroviridis IDs and protein sequences. The OMA Browser is now up again and fully working.

We would like to express our sincere apologies for any inconvenience caused.

Warning: TETNG (Tetraodon nigroviridis) has wrong IDs/sequences in current release

Dear OMA users,

Dr. Ingo Ebersberger (Center for Integrative Bioinformatics Vienna) brought to our attention that all TETNG (Tetraodon nigroviridis) IDs and sequences of the current release (October 2009) are wrong.

We are sorry for the trouble this may have caused.

At least, we found the bug, and we are confident that 1) no other species has the same problem, and 2) orthology predictions were not disrupted because of this problem.

We are now fixing the problem, and hope to have a new release ready by early next week. In the meanwhile, the other species should be fine.

Thanks to Ingo for reporting the problem, and to all of your for your understanding.

The OMA team
