Hi everyone,
I am trying to clean some data using ICA artefact removal on a 128-channel scalp EEG data. I’ve been following several tutorials on Brainstorm, especially https://neuroimage.usc.edu/brainstorm/Tutorials/Epilepsy#Artifact_cleaning_with_ICA
I can not seem to find anything specific to how to choose an acceptable number for ICA components.
The minimal number of components required seems to depend on sampling rate, length (time window) of the file and the number of channels.
After doing some research on google, I’ve realised that this varies between different softwares so I was wondering if anyone has come across this information for Brainstorm?
Healthy Regards,
Vyte
