Hi,
I am trying to figure out how to use 3dPC and what the output means. I have not been able to find any documentation, can you point me to something that will explain what I am looking at? There is one file for each time-point, does that mean each time-point is a component? (I would expect a component for each time-series, or some sub-set of them)
Also, it would be useful if there was a -mask option, so that voxels outside the brain can be excluded from the analysis. Can this be added easily?
Thanks!
Sara
