Do I need to apply ssp/ica when I import in database

Hi all,

I want to know if I should apply ssp/ica into my stimuli when I import them in the database? Thank you!

If you want the projectors you want to be applied to your recordings, yes.

If you are not familiar with these concepts, I recommend you start by following all the introduction tutorials (section "Get started" or the tutorial page) using the example dataset provided, before trying to process your own recordings.

I reread these tutorials again, and now I get it. Thanks so much Francois!
