Hello
To go around this limitation of the interface in Brainstorm, you can do something similar to what you do in EEGLAB:
- Import all the segments of data you want to use to compute your ICs (menu “Import MEG/EEG”)
- In Process2, select all the imported blocks in the left list (FilesA) and your original continuous file in the right list (FilesB)
- Run process Artifacts > ICA components
Cheers,
Francois
