Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

Hi Reynold,

Thanks for replying. There is 30s difference between early and late stimulation onset. And there is 60s gap in between end of late to next early stim.

i.e.= the stim_early_file= 20 140 260 380 500 (s)
stim_late_file= 50 170 290 410 530 (s)

I just ran the data considering a whole 60s block BLOCK(60,1).
The sum of early regressor coefficients (beta) and late regressor coefficients did not come as same as 60s BLOCK regressor coefficients. Not sure what I might be missing.
edit: just found out that you meant regressor not regressor coefficients. Let me check that and come back
