thanks, it seems to be exactly what I'm looking for.
How many time points do I need to perform this type of correlation? I have 8 time points per trial, and this is the message that I received when I tried to run it:
ERROR: Input dataset './0128136.CSPLINz.ThreatNoPic.1stHalf.IRF+tlrc.HEAD' is too short: 8 time points
I understand that these type of correlation might be well suited for resting state analysis or at least blocks of conditions that probably lasts few minutes, but is there something similar that I can do on on short time intervals?
thank you
