What kind of a NIFTI parcellation is this? Subcortical? Peace,

From: <[email protected]<mailto:[email protected]>> on behalf of "PALLARES PICAZO, VICENTE" <[email protected]<mailto:[email protected]>> Date: Friday, October 28, 2016 at 10:12 AM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: [HCP-Users] Extracting time series in grayordinates from any brain parcellation Dear HCP data users, We would like to use the fantastic resting state fMRI data set from the HCP :) We are interested in extracting the time series from the minimal preprocessing resting fMRI data to later perform our own analysis. After checking the available information, it seems that the most appropriate way to extract the average signal in each region of interest is to use the cifti-parcellate command. In the help section we have seen that the cifti-parcellate command has four arguments: wb_command -cifti-parcellate <cifti-in> - the cifti file to parcellate <cifti-label> - a cifti label file to use for the parcellation <direction> - which mapping to parcellate (integer, ROW, or COLUMN) <cifti-out> - output - output cifti file Our questions are: 1) For the <cifti-label> argument, how can we transform our nifti parcellation atlas into a cifti label file for both cortical and subcortical areas? We have seen that there is a wb_command -cifti-create-label command, but we are worried that for example our hippocampus label is different from the hippocampus label in cifti... So, is there any way to transform our nifti atlas into cifti without using the already determined CIFTI structures? 2)For the for <cifti in> argument, we use the file "rfMRI_REST1_LR_Atlas_hp2000_clean.dtseries.nii" from the folder 100307_3T_rfMRI_REST1_fixextended\100307\MNINonLinear\Results\rfMRI_REST1_LR . Is that correct?
