Thanks doug But I am not sure if it was the answer. To be more specific, my subjects did two different tasks within one fmri run. I want to see their functional connectivity during task 1 and task 2 separately.
If it was resting state, I didn't need to separate my data and a simple fcseed-config like below was enough: fcseed-config -roi Labels/rh.V1 -fcname mean.R_V1.dat -fsd rest -mean -cfg CFG_Files/mean.R_V1.config But now, I don't know how to modify my fcseed-config to say I have had two conditions (task) within one run and I need to measure the seed for each task separately.
