Corrupted release - Rollback to Sep2014 release

Dear OMA users,

We are very sorry to inform you that the latest release of the OMA browser ("Mar 2015"), which has been accessible since 5 June 2015, is unfortunately corrupted. Specifically, in species that were updated in that release, many homologous pairs were erroneously left out in the inference step. We are therefore retracting the "Mar 2015" release and are using the previous release from Sep 2014 again.

We are now in the process of preparing a new release but this process will take several weeks.

If you have any question whether your analysis might be affected, feel free to contact us

We are very sorry for any inconveniences this might have caused.

Kind regards,
the OMA team

New OMA release with 1850 species

Update: this release contained errors and has been retracted. More details here.

We have just released the latest update of the OMA Browser. It is the 18th release covering 1850 genomes.

In this release we added two new Primates (Chlorocebus sabaeus and Papio anubis), another fish (Poecilia formosa), 6 other animals (Loa loa, Onchocerca volvulus, Melitaea cinxia, Dendroctonus ponderosae, Megaselia scalaris and Drosophila sechellia) and 7 new plants (Oryza nivara, Oryza punctata, Oryza rufipogon, Prunus persica, Brassica oleracea, Theobroma cacao and Amborella trichopoda). In this release we updated again many common model organisms. You can find a detailed list of all the covered species on our website (

As usual, the data of the previous releases is still available for download.
