[EMBOSS] needle extended with reading frame information?

[David Bauer]

Hi,

did you try the EMBOSS tranalign ?

tranalign 	Generate an alignment of nucleic coding regions from aligned proteins

Kind regards,
David.

It might be more useful to you to align the protein sequences and then thread the corresponding nucleotide sequences onto that AA alignment "skeleton"

Translator X will do this for you automatically, given the ORFs, or you can provide a pre-run protein alignment if the alignment programs in TranslatorX are not suitable for you.

http://translatorx.co.uk/

You can either run on their server or, if your job is too big, download and install locally.
