EasyGene 1.2b Server

Gene finding in prokaryotes

The EasyGene 1.2 server produces a list of predicted genes given a sequence of prokaryotic DNA. The current version contains models for 138 different organisms. Each prediction is attributed with a significance score (R-value) indicating how likely it is to be just a non-coding open reading frame rather than a real gene. All that is required of you as a user is to supply the query sequence(s) and to select the organism model to use (see instructions).

The pre-calculated EasyGene 1.2 predictions for the complete genomes of the 138 organisms can be downloaded from the EasyGene site at BINF at the University of Copenhagen.

This version replaces EasyGene 1.0. View the version history of this server.

Would you like to gene train own models for other organisms than the 138 mentioned above? The EasyGene 1.2 training part is available as a stand-alone software package (for Linux only). There is a download page for academic users; other users are requested to contact CBS Software Package Manager at software@cbs.dtu.dk.
