So I guess I can add 72 days of calculation to this paper, or I can give up on having this one figure. Boo to me and my laptop.

Whatcha filtering? Can the computer nerds help?

Maybe? Reinstalling the latest driver that was already installed seems to have fixed the problem with matlab. I have no idea why this was the magic time.
I now have 3 different matlabs, which is honestly embarrassing but I can learn to live with it.

What I want to do is look at some phase amplitude coupling between a cortical and hippocampal LFP across a pretty wide range of frequencies (0.5 - 140Hz). I'm basing it on Tort et al., J Neurophysiol 2010 (https://github.com/tortlab/phase-amplitude-coupling)

For each frequency bin, there is a filfilt step, followed by a Hilbert transformation to get phase or amplitude, and then I calculate a modulation index for each phase/amplitude bin. I am not sure if the whole method is just very inefficient, or if it will just take a long time to calculate because of my data where I repeat this for a lot of epochs.
