Any way i can go around this error?

This causes thensorqtl to fail. I have 4 phenotypes, all 4 are dropped as there are no variants in the region that are passing the thresholds predefined. As all of thme are dropped there is nothing left to test and the thread gets stuck.

  * 1033 samples
  * 4 phenotypes
  * 6 covariates
  * 6100111 variants

I resolved it by doing this as per my pull request. master...maxozo:tensorqtl:patch-1
Untill this is merged i have made a copy of genotypeio.py with a patch and i load it from my local files instead of tensorqtl package.
