Greetings, I am trying to import data into BrainStorm but I am only interested in importing a few specific channels. I would appreciate it if someone could advise me on this.
Sincerely,
Ali
The import menus "Review raw file" and "Import MEG/EEG" do not allow you to import only a subset of the channels.
If your concern is about ignoring some channels in the display and processing within Brainstorm: right-click on the channel file > Edit channel file, then change the types of the channels to something else than "EEG".
If you want only some of the signals and use them in your own Matlab scripts:
once the data is imported to the database, you have access to everything as .mat files and can decide to use only a few channels in your data.

Dear Francois,
Thank you very much for your help. My main concern is importing a large data when I am only interested in vewing and processing a small subset of channels.
Best Regards
Ali
You can also use the low-level file readers directly: in_fopen / in_fread.
But this would give you signals, not files in the Brainstorm database.
Otherwise, you need to import the data in small chunks, or work only with the file as a continuous file (menu "Review raw file", which does not "Import" the file to the database).
