Hi professors! I'm trying to build a figure like 'custom_Mesh.jpg'
file you uploaded, but using the 'clipping' function, only similar
figure like 'medial.jpg' file you uploaded can be achieved? how do
u fill these hollow holes? using code or other functions?

You can also create a custom mesh with any regions removed that you
want. In the image 'custom_Mesh.jpg' I started with the
'mni152_2009bet.nii.gz' volume that comes with MRIcroGL
Use MRIcron to create volume where you have removed regions you do
not want to view
1. Draw to draw volume of interest
2. Draw/MaskImageWithVOI/DeleteRegionWithVOI
3. File/SaveAsNifti
Convert volume to mesh
1.) SurfIce (very slow for complex meshes)
Advanced/ConvertVoxelwiseVolumeToMesh
2.) MRIcroS File/AddLayer and select output of MRIcron,
File/SaveMeshes
Now open your new mesh.

The easiest solution is to use the meshes for the left and right
hemisphere provided with the software. Here is a sample script:
BEGIN
RESETDEFAULTS;
MESHLOAD('BrainMesh_ICBM152Right.mz3');
OVERLAYLOAD('motor_4t95mesh.mz3');
OVERLAYCOLORNAME(1, 'Red');
SHADERXRAY(1.0, 0.3);
AZIMUTHELEVATION(270, 0);
END.

Hi,
Related to this, is there a way to get L/R mid-sagittal slices that
don't have holes in the cingulate/cerebellum?
Regards,
Matt

Sure, open the image you are interested and drag the "Clipping"
sliders. For a mid-sagittal slice you will want a depth of 0.5, an
elevation of 0 and a azimuth of either 0 or 270 depending on
whether you want to remove the left or right hemisphere.
To demonstrate, here is a sample script (go to Advanced/Scripting,
paste this into the scripting Window and then invoke the scripting
window's Script/Run command
BEGIN
RESETDEFAULTS;
MESHLOAD('mni152_2009.mz3');
OVERLAYLOAD('motor_4t95mesh.mz3');
CLIPAZIMUTHELEVATION(0.5, 270, 0);
SHADERAMBIENTOCCLUSION(0.5);
SHADERXRAY(1.0, 0.5);
END.
