When using 3dGroupInCorr, is it possible to exclude a subset of the data in an existing niml/data file based on the labels applied to the data? Put another way, is it possible to generate an all-inclusive niml/data file with 3dSetupGroupInCorr, and then later consider only certain participants or sessions by filtering with labels at the 3dGroupInCorr stage? Thanks!
