[HCP-Users] Resting fMRI Cortex Vertices Indices

2015-05-31 Thread Chao Liu
Dear Experts, In resting state fMRI dtseries file, by using wb_command -file-information xxx.dtseries.nii, we could see: CortexLeft: 29696 out of 32492 vertices CortexRight: 29716 out of 32492 vertices … And by using wb_command -nifti-information xxx.dtseries.nii -print-xml we could see:

Dear Experts, In the resting state fMRI data, the subcortical structures have names such as amygdala(L or R). But for the cortical structures, I could only find names like “CortexLeft” and “CortexRight”. Can I get more detailed names like superior temporal gyrus (or brodmann areas) for the cort

Dear HCP Experts, I am inspecting the HCP rfMRI data. For each subject, there are two sessions with 2 runs (LR&RL) in each session, yielding 4 files in total. Although we can concatenate all the four time series and do the correlation, I found the memory needed is more than the memory I have on

[HCP-Users] Plot analysis results on HCP resting state fMRI data

2015-01-18 Thread Chao Liu
Dear experts, I would like to plot some analysis results (not in the HCP pipeline) on HCP resting state data. what I get is a N by 1 index vector IND whose length is equal to the number of vertices and voxels in the data. E.g., for subject 100307, there are 59412 vertices and 31870 voxels, so N
