Modulation in nilearn design matrix

1

Hi!

I have 6 event types, and I believe that there is modulation for 3 of them. Is it possible to create separate modulation columns for them? As far as I understood, in nilearn you can have only one modulation column in the events.tsv file. Should i put all the modulations in this column?

Best,
Anastasia

Dear Anastasia,
you can encode all modulation information in a unique columns. This will be processed separately for each condition. For conditions that have no modulation, simply import ones.
I hope I understood you point correctly. Don’t hesitate to ask more questions.

Dear Bertrand,

Thanks a lot for your response. If I’ll create 3 columns with the same name “modulation” will they all be used by nilearn?
