I am a beginner of using this software. I load in EGI 128 channel EEG into Brainstorm. I load GSN Hydrocel 128 E001 as channel file. I can view and pre-process to filter the data. However, when I try to run "Artifact" ICA component procedure, most sub-menus of SSP: heartbeats, Eyeblinks, Generic, ICA Components, Apply SSP and GTF compensation and Undo 4D/CTF noise compensation are grayed out. What procedure did missed or what caused my procedure not working?
All the SSP and ICA menus are only available for continuous files (= "Link to raw file").
You need to use the menu "Review raw file" instead of "Import MEG/EEG", as explained in the tutorials:

If you are not familiar with this concept, we recommend you start by following all the introduction tutorials in the section "Get started" using the example datasets, then read advanced tutorials related with your field of interest.
