Dear folks:
I ran MELODIC to the fMRI data, and have a bunch of spatial ICs as well as some time course. I observed those time course, but could see anything that are possiblly related to our task. Since the unmixing matrix is solved by FastICA basically, is it really obviously related to external task? ex. If my external task is like periodic spikes in time domain, am I supposed see there is one time course looking like periodic spike, and thus its fourier spectrum is concentrated at some certain frequency?
Thanks a lot
Xuelin
