RE: fMRI scans in multiband imaging dataset
Hello all,
I have another question regarding the checkerboard stimulation data in the multiband imaging dataset. I am using TR=1400 msec scans, and to conduct a group analysis, I am using the first 82 scans of each subject, discarding the extra fixation block for the subjects which have it.
Discarding the extra block at the end, we should have a total scanning time of 6 blocks*20 sec=120 sec. However, we have 82 volumes with TR=1400 msec, which gives 1.4 sec*82 volumes=114.8 sec. I want to make sure that I got the paradigm timing right, which is crucial when generating the task regressor. If I assign the paradigm for each volume using TR=1.4 and exactly 20 sec blocks, the last checkerboard stimulation block seems to have 10 volumes (14 sec). Is this right? If not, is the list of paradigms for each volume available?
Thanks in advance,
Burak
