Hello experts,
I am trying to convert insula ROIs that are in MNI 152 2 mm space to MNI305
space. I will eventually this ROI for connectivity analysis.
I ran mri_vol2vol:

Hello Freesurfer community!
I am trying to run fspalm on surface based data. I have installed PALM, fspalm,
mri_surfcluster, and mri_volcluster.
This is my fspalm command:

Yes, the fraction of the ROI the cluster is covering, not the reverse, so sum >
1 is ok. Eg, if cluster covers all of hippo and amyg, then both would be 1 and
would sum to 2.

Hello,
I have a large cluster in my group volume map (sig.mgh). I would like to know
what percentage of this cluster is in amygdala, hippocampus, etc. Is there a
command I could run that would give me that information?
Thank you in advance.

, --default-ctab, and your binarized
cluster as input. The "mean" column will then be the fraction of the cluster in
the ROI. Also, if the sig.mgh is 2mm in fsaverage space, then make sure to use
the aseg from the mri.2mm folder

I tried the way you suggested and the registration actually looks worse. I

It must be in the space of $SUBJECTS_DIR/fsaverage/mri/orig.mgz for that

Hi,
I am wondering if you would give some input on this:
When we run the buckner scripts for functional connectivity analysis, those
scripts:
1. Obtain correlation maps of individual subjects, and convert them to
individual subject z-maps
).
