combination_model_train.py Label and Chr fields

[slmcevoy]

Hi,

Just wanted to see if it would be possible to update combination_model_train.py to include Chr. Also, I've tried to run it but got errors related to a Label field. The readme says training can be done on per-read and per-site output from tools, but that output doesn't include Label, so I'm confused about what I should be using as input. I'm working on plants and would like to see how results compare if I train using random forest compared to the provided models.

Thanks!
