The ROI volume is not binary however I binarized it after mapping to the surface space. Should I have binarized the ROI prior to running mri_vol2surf?

another thing to check is that you are using a binary ROI file. The Volume based image looked like it had a range of values.

Hi Derek
I think the dev version of mri_label2label supports open/close/dilate/erode operations:
mri_label2label --help USAGE: mri_label2label.bin
--srclabel input label file
--erode N erode the label N times before writing --open N open the label N times before writing --close N close the label N times before writing --dilate N dilate the label N times before writing . . .
if your version doesn't have these operations let us know and we can get you an updated one
cheers Bruce

Hi Bruce,
As always thank you for your prompt reply.
For the morphological close operation, would you suggest using mris_fill on the surface ROI I created and then running mri_vol2surf again on the volume output by mris_fill?

p.s. you could remove many/most of these holes using a morphological close operation On Fri, 28 Oct 2016, Andrews, Derek wrote:
Hello Freesurfer Developers and Community,
I am looking to map a ROI.nii based on the MNI152 template to the fsaverage pial surface.
I have used the following commands
Bbregister ‹s fsaverage ‹mov MNI152.nii ‹reg register.dat ‹init-fsl ‹12 ‹t1
Then
mri_vol2surf ‹src ROI.nii ‹out ROI.mgh ‹srcreg register.dat ‹hemi lh
The ROI appears to be in the right place however is very blotchy. Have I missed a step? Or is this correct?
See bellow a picture of the ROI highlighted in FSL and in tksurfer after mapped using the above.
Thank you for your support,
Best, Derek
