Hi pt,
Thank you for the suggestion. After editing the text file according to your suggestion, a matrix with r values and z scores was generated.
There is one thing that still makes me confused though. In my analysis, there are two time points for each subject. I just ran 3dNetCorr for a single subject and in the .netcc output, there were 232 ROIs for time 1 and 249 ROIs for time 2, even though there were a total of 264 ROIs in the text file used for 3dUndump. Could you please let me know why this occurred?
Best,
JW
