How to get the correlation matrix of a ROI with the whole brain,

Submitted by cheungmen on Sat, 01/26/2013 - 02:24

prof. yan,
    I have a question when computing connectivity.
    I choose Functional Connectivity in the GUI of DPARSF, and click Define ROI, then click Run. but in the Results file, no correlation matrix can be found.

     I hope to get the correlation matrix of a ROI with the whole brain, but I don't how to do?

     I'm  forwarding to your reply,
     with my great thanks!

Hi, actually the correlation matrix (seed time course vs. all the other voxels) are stored into .nii image file format. e.g., FCMap***.nii
You can use rest_readfile to get the data.
