ICA sort components based on correlation results in only one component

Hi Francois!

I am testing the "Sort components based on correlation" feature in the ICA computation. I have ran this on several run (drag and drop several bandpass filtered continuous files in Process -> Run -> Artifacts -> ICA components) :

I have selected the channel EXG2 (VEOG) to sort the components and ran the process.
In result, I seem to have only one ICA component for each run.

I was expecting 32 ICA components sorted by correlation with EXG2.

Did I do something wrong?

Thank you!

That’s a bug actually. I only tested this feature with more than one reference channel… (e.g. ECG+EOG)

I submitted a pull request that fixes this issue https://github.com/brainstorm-tools/brainstorm3/pull/77

Merged.
Thanks!
