Failing to index VCF file

[acboulet]

I'm running Strelka to call variants in a plant genome, and receiving an error when Strelka tries to index the final VCF file. I'm not surprised as the BAM indexes require CSI formatting due to the plant genome. However, I'm unsure how to configure Strelka to allow for this option. Is there a way to change the tabix indexing or even prevent this step?

Below I've included a section of the my log with some directory information replaced.

Any advice on how to handle the VCF indexing would be greatly appreciated.
