Hello,
I would like to find correlation map in Resting -state FMRI using AFNI.
I tried to use 3dMaskAve and 3dfim+ for that.
Also, I used InstaCorr for the analysis, but I am not sure about several options in InstaCorr.
I want to use several voxels as an ROI (that is drawn as a nifti file in FSL), not just 1 voxel.
I am not sure if the "multiple voxels" can be used as an ROI instead of 1 voxel.
(From my understanding, InstaCorr can use single voxel as an ROI by clicking 'InstaCorr set' button.)
In InstaCorr Setup window, there is Misc opts menu, and when I clicked that, I can control 'SeedRad' .
Does 'SeedRad' mean that I can control the size of ROI in mm? Even though I clicked single voxel and clicked 'InstaCorr set' button, does AFNI calculate correlation using the resized ROI?
Thank you for your help.
