Hi Gaurang
it depends on what you are trying to fix. Is it cortical gray matter? If so, it is usually either the case that the underlying white matter is incorrect, in which case you fix it and the gray will be accurate, or the auto-detected class intensities are inaccurate. Can you send us an image or two?

To whom it may concern:
I had question about Freesurfer, I am trying to correct the gray matter volume. So I made changes by adding pixels to the contour, and ran recon-all. Subsequently, when I opened up the file after performing recon-all I saw were the pixels (which are white) that I added when I was making the changes. How do you make changes to the gray matter, and what type of recon command should I run after making the changes.
I searched through the various tutorials, but that further confused me.
Thank you for your time.
