I can get separate the volumetric part of cifti files with a command like: wb_command -cifti-separate ToyNogo_fdr_palm/ToyNogo_results_merged_tstat.dscalar.nii COLUMN -volume ACCUMBENS_RIGHT R_Acc_Beta.nii.gz -roi R_NAcc_ROI.nii.gz
But when I try that on surface data I get the error: wb_command -cifti-separate ToyNogo_GlasserParcellation_FLOBS1_fdr_palm/ToyNogo_results_dat_tstat.pscalar.nii COLUMN -label R_IFSp_ROI ToyNogo_R_IFSp_Beta.pscalar.nii -roi R_IFSp_ROI.plabel.nii ERROR: unrecognized structure type The problem seems to be in recognizing the structures name (i.e. R_IFSp_ROI). Do you know how I can reference a specific structure or structures with a command from a label file, or is there another comparable command you would suggest for isolating structures from a label file?

Furthermore, although it’s alluring to believe that a single parcel will encapsulate all of response inhibition, it’s doubtful. Why not select a set of parcels in and near IFG, and correct for multiple comparisons? Use a meta-analysis as your guide (https://urldefense.proofpoint.com/v2/url?u=http-3A__neurosynth.org_analyses_terms_response-2520inhibition_&d=DQIGaQ&c=lb62iw4YL4RFalcE2hQUQealT9-RXrryqt9KZX2qu2s&r=rPclmYysc_z1plf99IoNsmxWf1JolkKMmL6bXnYFSwg&m=Pb-c1m96L6xixMU-j16J-GkC6tGV5lAdGNKy-Tj1ht8&s=DxHCajoqQSf0nIWSDbUHyB6J7F2eax1NswvaNpprHaU&e= ). Your statistical power should still benefit from the parcellated analysis and reduced number of multiple comparisons, relative to a whole-brain analysis. --Greg ____________________________________________________________________ Greg Burgess, Ph.D. Staff Scientist, Human Connectome Project Washington University School of Medicine Department of Psychiatry Phone: 314-362-7864 Email: gburg...@wustl.edu<mailto:gburg...@wustl.edu> On Sep 27, 2016, at 9:26 AM, Michael F.W.

There is a lot of background of IFG being involved in response inhibition, particularly on go/nogo tasks,, so I was wondering if you had any information on specifically where within your parcellation that may be most relevant.

You indicated that you had a priori hypotheses about IFG involvement, but that doesn’t allow you to then select a particular IFG parcel based on your task activation map. Ideally, you would have selected your parcel(s) for analysis prior to ever computing/viewing your activation map (unless what you showed was a map from an independent, unrelated set of subjects). _______________________________________________ HCP-Users mailing list HCP-Users@humanconnectome.org<mailto:HCP-Users@humanconnectome.org> https://urldefense.proofpoint.com/v2/url?u=http-3A__lists.humanconnectome.org_mailman_listinfo_hcp-2Dusers&d=DQIGaQ&c=lb62iw4YL4RFalcE2hQUQealT9-RXrryqt9KZX2qu2s&r=rPclmYysc_z1plf99IoNsmxWf1JolkKMmL6bXnYFSwg&m=Pb-c1m96L6xixMU-j16J-GkC6tGV5lAdGNKy-Tj1ht8&s=Kd8JGIfyDD_MWOgH24WZFrQNLqIT2e2KIaFCaLTw3PM&e= --Greg ____________________________________________________________________ Greg Burgess, Ph.D. Staff Scientist, Human Connectome Project Washington University School of Medicine Department of Psychiatry Phone: 314-362-7864 Email: gburg...@wustl.edu<mailto:gburg...@wustl.edu> ________________________________ The materials in this message are private and may contain Protected Healthcare Information or other information of a sensitive nature.
