Hi Esben. Sorry I didn't see your posting earlier.

So far I have just hand edited the PIR file from a fasta file, but now I'm trying to model a multimeric and multidomain protein which makes it very complicated and cumbersome. Jalview (http://www.jalview.org) makes an attempt at preserving the PIR comment lines specifically for this purpose. There is also a setting in the preferences to enable 'modeller style PIR' output, which means that it will try and keep the sequence start/end numbering in sync with the residue numbering entries in the information field.
hope this helps. Jim
