Hi,

I am new to both AFNI and Ubuntu(on Windows). I want to make 18 ROIs and extract various data on these 18 ROIs like correlation matrix, avergae time series etc.

I tried the following and it didnt work.

I saved a txt file with the xyz coordinates of all 18 roi.'s 1 in each line. I also added a number as a 4th dimension. Then used 3dUndump to make a mask but now when i run 3dNetCorr it gives me an error that it needs more that 1 sub brick.

How can i workaround this problem.
