EasyGene 1.0 Server

Gene finding in prokaryotes

The EasyGene 1.0 server produces a list of predicted genes given a sequence of prokaryotic DNA. 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. The user needs only to specify the organism hosting the query sequence. Two more parameters (start codon leniency and R-value cutoff) have default values which may be altered if needed.

For organisms not listed in the menu below (and for the newest version of EasyGene with enhanced output features) please go to EasyGene1.2 predictions

Update Jan 2007: EasyGene 1.2 is also available as a local stand-alone version upon request. Please enquire by e-mail to Thomas or Kristoffer below.

Instructions Output format Article abstract


Paste a single sequence or several sequences in FASTA format into the field below:

Submit a file in FASTA format directly from your local disk:

Start codon leniency      R-value cutoff


The sequences are kept confidential and will be deleted after processing.
