Dear All!
How can I extract the RAW time series of some ROIs from task-based spm.mat? Here I don't want to extract the time series from a specific contrast. I want to extract the original time series before being adjusted by contrasts. So should I treat my task-based spm.mat as the resting state spm.mat? and follow the steps described in spm manual in the dynamic causal modelling of resting state
also I'd like to know how ROIs time series are adjusted by the contrasts. For instance, in spm's manual auditory data example, if I extracted the time series from [57 -22 11] in listening>rest contrast, will it be the same as in listening>0? No, they are different so how was the time series in [57 -22 11] estimated?
one more question, did any one manage to extract the time series of all brain voxels? and is there a template for all brain ROIs?
Thanks,
maaly
