Hi, Bruce
 
Do you mean that if the tumor located in the subcortical area, there is not large impact to reconstruction; if the tumor located in the cortical regions, there will affect the cortex reconstruction?
 
Another question is that I have MRI data from stroke patients. However, there are different lesions in the brain across the patients, including cerebral cortex and subcortical area. How could I perform reconstruction analysis?
 
Best,
Feng

Hi Feng 
 
it depends on where the tumor is
