Dear all experters,
First I am appreciated for the help of Bruce. I tried to following his instruction, but I still have some problem and I can't show any result on the flated surface. I don't know whether my method to calculate the volume is wrong or I display it wrongly. Expecting someone gives me a struction again! My method is: using *read_curv* function to read* lh.thickness* and*lh.area *. Then the matrix of thickness product the matrix of area getting a new matrix. Then using *write_curv* function to write this new matrix into a *.volume. I think this volume file should be the grey volume image. (I am not sure about this process) And now I want to show this volume on a flated lh hemispere (using tksurfer), But when I overlay this volume onto inflated surface, there is not anything overlay on this surface? (this matrix is not all with 0. )
Anywhere am I wrong?
Any instruction will be appriciated!

Dear developer,
I want to compare the grey matter volume by VBM to cortical thicknessby freesurfer. But in this process, I meet a problem: how to change the points number of grey matter into the same with the vertex of thickness by freesurfer?
Any help will be appreciated! Best regardsJoe
