How to draw symbols which indicate stimulation locations on rendered brain

Thank you very much!

It’s crucial for me to set the appropriate size of ROIs. However, my sufice automatically zooms nodes whenever I add nodes.

I am unsure how much I need to slide the slider in order to achieve the desired size of nodes specified in the .node file. And we can’t also input an exact value to adjust the size.

Moreover, when I attempt to minimize the zooming slider, error messages start popping up, and the 3D mesh becomes unresponsive after pressing any of the buttons: OK, cancel or abort.

Besides, I tried to use the code to set the size:

import gl
gl.resetdefaults()
gl.meshload('cortex_20484.surf.gii')
gl.azimuthelevation(110, 15)
gl.shadername('MatCap');
gl.meshcurv()
nodeload('test.node') 
nodesize(8, false)

It doesn’t work.
The error messages said: NameError: name 'nodeload' is not defined.

My node file for testing contains:

 0   60   60   30   8     tq
 20  60   60   20   8     ew
 40  60   60   10   8     se
