This might be a somewhat amateurish question. I have resting state and task datasets of some subjects and I want to compare these two for a rest vs task analysis of their power-law exponents. TR=2 s for both. But the resting state data has 148 time points and task has 330 (110 time points for each of the 3 runs). Can I compare those two (148 vs 330 time points) or should I select 148 time points out of that 330 task time points (probably somewhere in the middle with a code like 3dbucket -prefix cooltask longtask+tlrc[115-262].)
Thanks,
Yasir
