How to run it?

There are two option to get data out the MAdb. Option one is to select one of the given species and option two is to select a list of IDs. This ID list can only contain one of the following ID types at ones:
  • EntrezGeneID from NCBI
  • Gene Symbol (official HGNC Symbol)
  • Ensembl gene ID from Ensembl
  • RefSeq (NCBI RNA Accession) [coming soon]
In order to retrieve the best output we recommend to perform the following steps:
  1. Run gene IDs (list) only with "GeneSymbol match"
  2. For the remaining gene IDs run "Ensembl Compara" and check manually on duplicates (most-likely the first hit is the correct hit), delete unclear duplicates, or remove all duplicates
  3. For the remaining gene IDs run "BLASTn comparison" and check again on duplicates
The output will be a selected table of ortholog genes from either your list or species of interest.
