When you  use --regheader, you should pass the name of the subject (not a volume); use whatever you passed to recon-all with the -s option. The output needs to be a volume (eg --o path/lh.something.mgz) On 7/11/2022 4:00 PM, Rachel Wagner wrote: External Email - Use Caution Please d

Pick a hemisphere (either lh or rh). Also, you should verify that your volume overlays on fsaverage correctly with something like tkmeditfv fsaverage orig.mgz -surfs -fminmax .01 1 -ov rReslice_Combined_roi_meanRD.nii  -reg $FREESURFER_HOME/average/mni152.register.dat On 7/11/2022 6:23 PM, R

There is not a way to do this automatically as part of recon-all. You would need to build a new gca by labeling a set of subjects then building the gca with gcatrain. On 7/12/2022 1:00 PM, Ramtilak Gattu wrote: External Email - Use Caution Hello all, We built a CC mask with 3 segmen

The contrast will test for the difference in slope of thickness vs NPIDSEV effect between AD and MCI or AD and CN. if it  is positive, it means that AD has a greater slope than MCI or CN. Note that this does not make a statement about the sign of the slopes so you can get a positive result when
