Hi all,
I am conducting a resting state fMRI analysis. I preprocessed the data using fMRIprep and denoised the data using AFNI. I would like to create 264 spherical ROIs centered around the MNI coordinates provided by Power et al. (2011; [
www.sciencedirect.com]).
My preprocessed images are in MNI space (MNI152NLin6Asym) with 2x2x2 mm resolution. To create each ROI, I used the following code with 3dUndump:
3dUndump -prefix ${name}.nii.gz -master sub-001_task-rest_space-MNI152NLin6Asym_res-2_desc-preproc_bold.nii.gz -srad 5 -xyz -24.66 -97.84 -12.33
Can I use the MNI coordinates directly from the paper to create each spherical ROI (as done above)? Or do I need to do an intermediate step to transform the coordinates to my image space?
Thanks in advance,
Jenna
