So I followed the following tutorial exactly to make the changes to the white matter. If there is a another way not shown in the tutorial, can you please let me know. I would greatly appreciate it.

sorry, I still don't understand. Which file are you adding white matter to? From the image you sent it looks like you are drawing on the brain or one of the similar ones, which is not what you should be doing. You should load and edit the wm.mgz

I made the necessary changes to the white matter, and when I ran recon all the changes with the voxels showed up, but there was no change to the contour lines. In order to change the gray matter volume, I can¹t find the changes I already made on the white matter (the picture with green control points). If I am able to see the changes I made to the white matter, I can utilize the control points to modify the segmentation. Also will this impact the gray matter volume as well as per your previous response to my question.

Thanks,
