New Release with 1320 species

We have finished the computation of a new OMA release including now orthologs among 1320 genomes. Besides 116 new genomes (including metazoans such as the atlantic cod, the ant and chinese softshell turtle) we again have updated many important eukaryotes, i.e. C. elegans, fruit fly, mouse, dog, pig, chimpanzee, honeybee and the rabbit genomes.

From this release on, we slightly adapt our orthology inference pipeline. Now, we do no longer test whether genes from species belonging to different kingdoms are apparent orthologs because of differential gene loss (our "witness of non-orthology" verification step). The rational for this decision is that the necessary duplication event must have happend prior to the speciation event of the two species in question, i.e. before LUCA, and hence these cases are not very reliable witnesses.

The data of the previous release is still available in the OMA Browser Archive for download.

Coming up: new release with 1320 genomes

Dear OMA users,

we have finished the computation of a new data set with 1320 genomes.

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

Service back to normal

We could solve the problems with the infrastructure. The OMA Browser is now working normally. Our apologizes for the inconveniences cause by the interruption.

OMA Browser website currently down

Due to a network problem, the OMA Browser is currently not reachable. We are working on it. We apologize for the inconvenience and will add a post as soon as the service is back to normal.

New Release with 1211 genomes

We have finished the computation of a new data set including now orthologs among 1211 genomes. Besides 103 new genomes (including metazoans such as the tree shrew, the tasmanian devil or the gibbon) we again have updated many eukaryotic genomes, i.e. the yeast, the frog, the gorilla or the human genomes.

Although the computation of the dataset has already been finished a while ago, the dataset is only accessible now. We apologize for this delay. We realized that we have hit the limits of our server. Hence, we first needed to upgrade our server and used the chance to also improve the implementation before releasing this new version.

The data of the previous release is still available in the OMA Browser Archive for download.
