Why FCmap can't show up after doing all of "functional connectivity" analysis?

Submitted by chlai on Wed, 04/28/2010 - 00:18

Dear all:

I did the functional connectivity analysis by REST v1.3 and I found that there were no so called "FCmap" in the results directory and fold. I used SPM statistical T-MAPs derived from GIFT toolbox as ROIs and I also finisehd the DPARSF preprocessing except ReHo, ALFF, etc. Can anybody tell me what's going wrong about this errors?
Thank you.

Dear Dr. Lai,
       Maybe you performed ROI-wise Functional Connectivity? Then no FCMap images will be created but some text files.
       Or have you encountered any error in the MATLAB command window?
       Best wishes!

Dear Dr. Yang:
Thank you for your kind reply.
Like you said, I used ROI wsie method.
I found the text files.
However, if I want to create the FCmap img files, what should I do for this purpose?
Thank you.

Dear Dr. Lai,
        Please click Voxel-wise first, then set the ROI, finally you can get the voxel-wise FCmap image (the correlation coefficient between each voxel in the brain and the seed ROI time course).
        There is a video in http://www.restfmri.net/forum/Course which may be helpful for you.
        Best wishes!
