"ValueError: invalid literal for int() with base 10: '-'" When running phmm.HmmHandler() with multiple tastes in params

[danielsvedberg]

Attempted to run HMMs with all tastes bundled into one model. (with params[{'taste':['Suc','NaCl','CA','QHCl']) Everything runs ok until it's time to save, then I get the message:

ValueError                                Traceback (most recent call last)

ValueError: invalid literal for int() with base 10: '-'

Will re-run on desktop with looser params to debug
