Hi HCP users, I am currently working with rs-fMRI data and have some questions regarding the parcellation scheme label file provided by HCP, specifically the file named "aparc.a2009s.32k_fs_LR.dlabel.nii"
Firstly, when using the two workbench commands: "wb_command -file-information 109123.aparc.a2009s.32k_fs_LR.dlabel.nii" and "wb_command -nifti-information -print-matrix 109123.aparc.a2009s.32k_fs_LR. dlabel.nii" I get a discrepancy between the dimensions of the image file between these two commands (59412 using -file-information vs. 59411 with -nifti-information). I am thinking this may be related to the manner in which these commands utilise 0/1-based indexing, but clarification on this would be appreciated. Secondly, using the -file-information command on this file " 109123.aparc.a2009s.32k_fs_LR.dlabel.nii" seems to output a list of regions/labels (150 unique labels in total), however when I extract timeseries from the HCP provided ICA-FIX cleaned data, the output is timeseries from 148 unique regions. I would like to know whether any regions have been excluded (medial wall perhaps?), which would account for this difference? Thanks for your assistance. Best, Ari _______________________________________________ HCP-Users mailing list [email protected] http://lists.humanconnectome.org/mailman/listinfo/hcp-users
