## Description


When using the Rest API to get the groups for "rat", it mentions the group HSNIH-Palmer.
But the REST API to obtain the geno file(http://gn2.genenetwork.org/api/v_pre1/gentotypes/HSNIH-Palmer.geno) failed.
The file of HSNIF-Palmer has actually a different name from what is expected; we have to use "HSNIH-Palmer_true" instead.
On GeneNetwork website, the following query does not return results from the search.

Issues with genotyped data:
Used this query:

Species: Rat
