I'd be interested in retrieving via Biomart the protein length associated to a transcript, as per screenshot below

![scrennshot][1]

I have retrieved the list of attributes available from biomart but can't seem to find the right field. 
Can someone confirm if this info is accessible programatically ? how ?

Thanks,

Hi iatz,

You can't retrieve protein length directly from BioMart. However, you can retrieve the CDS length and divide by 3.
