Dear AFNI experts,
I am interested in analyzing the correlation matrix between nodes using Power et al. (2011). There are 264 regions of interest in the Power atlas.
Power, J. D., Cohen, A. L., Nelson, S. M., Wig, G. S., Barnes, K. A., Church, J.
A., . . . Petersen, S. E. (2011). Functional network organization of the
human brain. Neuron, 72(4), 665-678. doi:10.1016/j.neuron.2011.09.006
I used the below 3dUndump script and a text file that has all the x,y,z coordinates from the Power paper to create nodes.
3dUndump -master /subj/errts.subj.fanaticor+tlrc \
-orient LPI \
-prefix nodes_264 \
-srad 5 \
-xyz powerrois_264.txt
The above script created a single tlrc file with all 264 nodes. After creating the spherical regions of interest, I used 3dNetCorr script below.
3dNetCorr -inset /subj/errts.subj.fanaticor+tlrc \
-prefix subj.netcorr \
-in_rois nodes_264+tlrc \
-fish_z \
-ts_out -ts_label -ts_indiv
The .netcc output file looked like below, which I think is weired.
# 1 # Number of network ROIs
# 2 # Number of netcc matrices
# WITH_ROI_LABELS
001
1
# CC
1.0000
# FZ
4.0000
I was expecting to have a 264 x 264 correlation matrix (z score) between the regions of interest from the .netcc output. Could you please let me know what would be an issue here?
Best,
JW
