Hi, Thanks for the input, I have been able to retrieve a lot more data this way! The first method doesn't give a full mapping however, but I will try the second one this weekend and see how that goes. The so-called IPI-index doesn't come near your solutions (http://www.ebi.ac.uk/IPI/IPIhelp.html), so you've been a great help!

The 'best' two solutions I finally found were; 1) Use SRS to map from RefSeq -> uniPark -> SwissProt (can't find where to get unipark from directly) 2) Use SeqHound to get SwissProt from GI. I was shown the SRS method, e.g. http://srs.ebi.ac.uk/srsbin/cgi-bin/wgetz?[UNIPARC-refdbi:NP_001102]%3ESWISS PROT And I got the following instructions on the use of SeqHound... If you want a list of GI's that have *exactly* the same sequence as your input protein GI, then you could use 'SHoundRedundantGroup' http://www.blueprint.org/seqhound/api_help/apifunctsdet.html#SHoundRedundant Group The Perl version of this takes a GI as input and then returns a list of GI's. You could use SHoundSeqIDFromGi (or SHoundSeqIDFromGiList) to find the Swiss-Prot sequence. Using either of these should get you a full mapping. Let me know how you get on, Dan. > >Thanks in advance, > >Joke Reumers > > >_______________________________________________ >Biodevelopers mailing list >Biodevelopers at bioinformatics.org >https://bioinformatics.org/mailman/listinfo/biodevelopers > _______________________________________________ Biodevelopers mailing list Biodevelopers at bioinformatics.org https://bioinformatics.org/mailman/listinfo/biodevelopers
