Genbank --> Locuslink - (Apr/18/2005 )
I have a large list of genes that have the Genbank number and the Affy probe number as the identifiers. Unfortunately I need the Locuslink Identifier for all those genes.
I could look them up individually but this is tedious and will be a recurring problem as we generate more and more data. So my question is is there any way to look up this information in an automated fashion or some kind of database that will look it up in a batch manner.
Edit: These are mouse genes from the Affy MU74 series of chips.
Yes you can.
You have to download a file called ac2lc (I guess) from NCBI FTP site. Then run a perl script to convert ac number to locus id. Once I did it for a friend. I may do it for you or send the script (after modification) to you so you can run it yourself.

Poked around on the ftp site could not find the file or anything similar sounding
Check here
ftp://ftp.ncbi.nih.gov/gene/DATA/
Please note, LocusLink has retired, now the file gene2access, gene2unigen, gene2refseq. Once you have gene2access, you can look back.

But if we want to know all transcripts names when we have genes names ( or Affymetrix probes names) , which informations can we extract from gene2access file?
