For example: def select_subset(ds, reselected_indices): ds_indices_tuple=map(tuple, ds.fa.voxel_indices) reselected_indices_tuple=map(tuple, reselected_indices) ds_keep_indices=[i for i, index in enumerate(ds_indices_tuple) if index in reselected_indices_tuple] return ds[:,ds_keep_indices] I hope that helps.
