Tried posting a table but it messed up my message. In case you cant see it:
Hi there,
Im new to fMRI in FSL, and am trying to figure out the following:
I have a single 4D niftii file that contains my aquisition for 4 blocks, with the last two being the same. Within these four block, I have two different types of stimuli presentation. So so far, we have 4 blocks, with a total of 6 different types of stimuli presentation. I think that would make it 6 evs to be compared. My design matrix would look as seen below. Block 1 consists of V1 and V2; Block 2 of V3 V4; and Blocks 3 and 4 of V5 and V6.
Now, I have a specific time file that tells me when each of these EVs has been presented. These times are listed in ms but can easily be converted to seconds. While they all have the same onset period and offset period, I want to be able to tell my FEAT query when each of these since the presentations within each block are randomized.
Any advice on how I can do that?
Ryan
