Gene id conversion

• List of some external tools and comparison
  • David and Matchminer were the best ones when compared with 100 random identifiers

• With biomart http://www.biomart.org (probably the best if your source ids are from Ensembl), click on:

1. 1. martview (top-right of screen)
   2. ensembl56 genes
   3. (select your species)
   4. "filters"
   5. "gene"
   6. paste your ids into "id list limit"
   7. "attributes"
   8. "GENE"
   9. uncheck "ensembl transcript id"
   10. uncheck "ensembl gene id" if you want to get rid of it
   11. "EXTERNAL"
   12. check "HGNC symbol" (or "HGNC automatic gene name" if not human)
   13. "results"

• With UCSC tools: thread (best option if your source IDs are UCSC knownGenes or if you prefer the table browser to biomart)
