_best_test_indices fail

fifthwave project page

_best_test_indices is failing as min can't work on an empty list. There needs to be some sort of get out clause here, but I'm not exactly sure what is causing the problem yet.

Solved the immediate problem of the script failing by putting a number of catches in for when the system can't find two good points to evaluate the celerity with. One of the problems seems to be with estimating the zero crossings so I'm going to start a new feature looking to improve this so that maybe they look for an average value rather than the absolute zero line.

Put in some cheap "pressure valves into the celerity stuff. Its generating no results at the moment though which is suspicious. I think maybe the return on line 499 is too strong.

Going to try and choose an average height for the zero crossings and see if that helps.

It seems like the zero crossings are the big issue here, in that with a very poor wave form it is almost impossible to identify them. This is cause stuff that is dependant on these, ie everything but mostly the celerity to not generate data.
