Thanks, Bruce & Kevin,

What I meant is that
1. I have an overlay image (FSL functional image overlaid onto
Freesurfer inflated image). So, the image has both functional and
anatomical in it.
2. I found an area of interest in the overlay image and I'd like to get
(functional) statistics of that particular area regarding amplitude of
activation.
3. I am asking if such a method is available on TkSurfer or TkMedit, or I
should do some other methods.

Thanks always.

Nam.

do you mean specifying it anatomically or functionall? You can do both. 
Anatomically you can use any of the cortical parcellation or subcortical 
segmentation units for this, or draw one yourself.

Hi All,

Is there a method of isolating an area of the overlay image (functional
    

onto
  

anatomical) on Freesurfer as ROI and get the average of the amplitude of
    

the
  

ROI?

Any suggestions would be appreciated.

Nam.
