Pandas.DataFrame.to_csv() unexpected argument sparsify

[kwkroll32]

Received an error writing vcf output. Apparently pandas.DataFrame.to_csv() doesn't accept the "sparsify" argument (anymore?). Not sure what it is supposed to do, but commenting it out stops the error and still produces a vcf file. If we can't remember where this came from, I propose we remove that argument from this particular to_csv call.

Pandas 0.19.1
See the offending line in output.VCF here

I can’t even find this parameter in the OLD version of pandas documentation. . Probably was undocumented parameter — how did you even find it? . Agree with removing but need to figure out what it will do. pandas manual has a section of sparsified data structures. HAs to do , I think, with multi-indices.

I got that error by simply trying to write vcf output. Something about my current environment must be different than before - Pandas 0.17 vs 0.19 maybe?
