Dear AFNI experts,
The output from 3dNetCorr includes a "graph dataset" of .niml.dset, which can be used for SUMA visualization of the connectivity matrix. However, my connectome includes a lot of ROIs that I want to filter out in this SUMA visualization. I am wondering if there is a convenient AFNI command to filter the .niml.dset, only keeping connectivity measures across a specified subset of ROIs.
