[EMBOSS] ORF selection with EMBOSS

[Hervé Ménager]

Hi,
I have been using transeq and checktrans to find ORFs in DNA sequences. 
I have an question regarding the selection of the ORFs in case 
checktrans finds multiple ones in the result of transeq: I would like to 
select the longest one automatically (assuming it is the correct one). 
Is there any existing tool in EMBOSS (or alternatively in any Bio* 
library) that does this job?
Cheers,
Hervé
