Giving error 'not all covariance entries are finite', unclear how to fix #3

Open danielpollak opened 6 years ago

danielpollak commented 6 years ago

For some data sets, the analysis will fail with a 'not all covariance entries are finite' error in spikoclust_gmem_covfix.m. It is unclear what if anything can be done to remedy this, nor is it clear where this error originates from.

Are you running the fully automated sorter or doing things stepwise per http://spikoclust.readthedocs.io/en/latest/usage.html#stepwise-sorting ? It's possible something is getting borked between spike detection/signal conditioning and the clustering step. I would check to make sure the spikes look reasonable before proceeding with clustering.

I was running the fully automated sorter. I can do stepwise though. Would you recommend doing anything besides changing around the filter?

Also, can you give me an idea of what the error I got means?
