I&#39;m trying to set up an analysis using an external regressor (as part of the mkanalysis-sess stream, -taskreg flag)  in version 5, but I&#39;m not sure what the taskreg.dat file should look like.  The only thing I can find is that it should have a line for each time point.  Does anyone have any more guidance than this?<div>
