Hi, JW-

The updated 3dNetCorr is now in the distribution, which was just rebuilt this morning. So, if you type
@update.afni.binaries -d
you should be able to get the new version (version number >= AFNI_21.2.06).

There are 2 new options, and I suspect you will want to use both simultaneously for having a "complete" NxN matrix output, even when some of the N ROIs are completely filled with time series that are all zeros:
-allow_roi_zeros   :by default, this program will end unhappily if any ROI
                      contains only time series that are all zeros (which
                      might occur if you applied a mask to your data that
                      is smaller than your ROI map).  This is because the
                      correlation with an all-zero time series is undefined.
                      However, if you want to allow ROIs to have all-zero
                      time series, use this option; each row and column
                      element in the Pearson and Fisher-Z transformed
                      matrices for this ROI will be 0.  NB: you cannot
                      use -part_corr when this option is used, to avoid
                      of mathematical badness.
                      See the NOTE about this option, below

  -automask_off      :if you do not enter a mask, this program will
                      make an internal automask of where time series are
                      not uniformly zero.  However, if you don't want this
                      done (e.g., you have a map of N ROIs that has greater
                      extent than your masked EPI data, and you are using
                      '-allow_roi_zeros' to get a full NxN matrix, even if
                      some rows and columns are zero), then use this option.

Please let me know how it goes.
