Just sample the activation onto the full surface (eg, --surf white --projfrac 0.5), then just load it as an overlay when you view the patch in freeview

External Email - Use Caution

Hello Freesurfer team,

I have flattened the occipital patch using "mris_flatten -w 10 subj04/surf/lh.occip.patch.3d subj04/surf/lh.occip.flattened" and it worked without any error and I can load the flattened patch in freeview. However, I have difficulty overlaying the activation map onto the flattened surface. Is the following command correct for this purpose? (mri_vol2surf --mov   spmT_0001.nii --out  subj04/surf/lh.bold.flat.mgz  --reg  fsl_reg.dat.lta   --surf occip.flattened  --hemi  lh)

Many thanks,

Atena
