External Email - Use Caution

Hi there,

I obtained a seed region (left superior frontal)from anatomical data to process resting state fMRI data as follows: fcseed-sess -o lh.SFC.dat -segid 1028 -s session -fsd rest.

I wonder if what the seed region is the left superior frontal was correct.

Question1: Can I display the lh.SFC.dat as MR image (anatomical image) using Freeview?

When you run fcseeed-sess, add -make-mask to create a binary mask in the run folder. You can then load this onto the anatomical to verify

I'd like to obtain ROI region as a seed region from anatomical data to process resting state fMRI data.

Question2: How do I make the seed region if I use 8-mm radius spheres centered on a MNI coordinate [x=20, y=20, z=20] as the seed region.

You need to transfer those coordinates to the individual subject's anatomical space (see #8b from https://surfer.nmr.mgh.harvard.edu/fswiki/CoordinateSystems), create your sphere in that space (mri_volsynth with spherical PDF), save this volume in subject/mri, then reference this volume when runing fcseed-config

Thanks,
