hmrR_tCCA unable to run
I have been unable to run hmrR_tCCA for my dataset with both short channels and accelerometer. This error appears:
"Function hmrR_tCCA generated error at line 129: The product of the downsample factor Q and the upsample factor P must be less than 2^31."
I am unable to figure out what is causing the problem, and would really appreciate any help I could get!
My processing pipeline and dataset can be found here: https://drive.google.com/drive/folders/1iV0PKjJZ8YSReRqfa0GpeevrJ81RfVqF?usp=share_link
Thank you so much!
I am running Homer3 v1.58.0, R2021a on Mac.
You need your resting run and functional run(s) under the same subject folder to be able to run tcca. I only see one file there.
@nehohmee, I see that the channel info don't show up for the resting run you put on gdrive (see attached figure). How did you cut the data? I resegment it using the homer segment tool, then renamed the files as 1resting and 2functional, then tcca worked. Also looking at your config file, you have kept the default [1 2 3 4] for tcca_aux_ind, however you only have two auxiliary channels in the file you send. This will break the code. If you want to use those aux channels as your regressors, you need to put [1 2]. (Since I do not know their content, I cannot say whether to use them or not.)
Hope this helps.
