Thanks for your reply Gang!
My experiment is visual motion adaptation paradigm, so there are adaptation phase and test phase in a trial.
Specific design is that, in a trial, there are 36-sec adaptation phase, 12-sec blank phase, 4~6-sec test phase, and 2-sec blank phase, which of four phases are 8 times repeated in a run.

My interest is the test phase in which participants see motion aftereffect (stim_label 17 to 20).
The long Stim_label 1 to 16 are about adaptation phase that consisted of 8 stimuli conditions and of initial (36 s) / top-up (12 s) adaptations.
I used trial-wise beta estimates for MVPA input data so that I used 'Stim_times_IM'.
I'm doing MVPA with raw signals as a MVPA dataset, and I found '.fitts' data clearer than raw signal.
So I'm wondering if I can use '.fitts' output as a MVPA data and if I remove motion parameters in regressors if I use '.fitts'.
Thank you!!
