pop_roi_connectplot erases EEG structure #82

Open amisepa opened 4 months ago

amisepa commented 4 months ago

After computing POwer and FC at source level, I try to plot with EEG = pop_roi_connectplot(EEG, 'measure', 'roipsd', 'plotcortex', 'on', 'freqrange', [8 13]);

And it gives this warning and erases everything... Warning: EEG.roi.cortex does not contain the field "Faces" required to plot surface topographies.

You could try our test_pipes/pipeline_connectivity.m test script that uses a source model with a compatible atlas (= one that contains a Faces field).

Sorry that it erases everything though, that shouldn’t happen. Not sure if that’s a Matlab thing but we can try to make it at least not delete the whole struct. Could you please also point me to the line where this error message is triggered in the function?

I was using 'LORETA-Talairach-BAs.mat' to compute the leadfield matrix, whereas the pipeline uses 'head_modelColin27_5003_Standard-10-5-Cap339.mat' But then pop_roi_activity uses the 'LORETA-Talairach-BAs' atlas. That's why I was using it for the field to match. Shouldn't they match?

NOte that Faces can be found in EEG.roi.leadfield.tri which may work with any atlas and avoid this issue since this is from leadfield.

Actually it is empty with the Talairach atlas so that doesn't work. I'll just use the Colin atlas
