Example for Training from New Alignment?

Hello,

I'm hoping to use DeepSequence to predict the effects of mutations, but can't find an example for how to train a model for alignments other than those tested in the original paper. For instance, it appears that `run_svi.py` will train  model using the "BLAT_ECOLX" dataset. What is the best way to modify this code to train a model using a new .a2m file? 

Thank you!
