Error loading frame for modelPreprocessMovie

[dprotter]

Hi there, I've been trying to get ciatah working on my ubuntu 20.04 machine. After some tinkering I've got videos loaded and can even take a folder with a bunch of UCLA miniscope avi files through the viewMovieRegistrationTest step.

However, when I try and run that same folder with the same regex strings through modelPreprocessMovie I get a blank image for selecting the ROI for motion correction. If I drag and double click anyway, i get an indexing error (see below).

I'm not 100% sure of the workflow here, if it would be better for me to try and downsample and convert to h5 first (running modelDownsampleRawMovies throws no errors but produces no output). Any help would be greatly appreciated!

Thanks for reaching out, could you send an example avi (e.g. just a Box or Dropbox link)? And is this a color (RGB) AVI? That'll help me debug what the issue is as CIAtah should support most AVIs unless not supported by the OS or certain specific codecs.

Thanks for that fast reply!
Heres a test video. i left it un-concatenated the way it comes off the scope, but could concat with ffmpeg if thats a better fit for ciatah. Encoding is ffv1. Ive gotten it to play directly with gstreamer, so I have the correct codecs. It also works in the viewMovieRegistrationTest step (including selecting the MC ROI).

I took another look today and realized theres a similar "variable does not support dot indexing" error raised in io.readFrame (139) for the avi case. I know you said it wasnt optimal, but things do run if I comment that same thisFrame.cdata line out.

-edit- However, it still doesnt work for a folder with a list of files (like the one I added to google drive), where again it fails to retrieve a frame for drawing the MC ROI.
