Hi there,
just a quick question about the regression of white matter signal from the fMRI data set. Can I just add the white matter timeseries to the text file containing the motion parameters (including fsl_motion_outlier) and then add to feat with "add additional confound EVs", or do does the timeseries need to be put into the EVs field to be convolved with a HRF.. What's confusing me is that the white matter signal comes from the BOLD, so it shouldn't need to be convolved, but then it's white matter...
Thanks very much in advance.
Best wishes,
Torsten
