Dear Bruce and All,

 

       In my View--Configure....there are three button which are activated (Light, caption and phase Encoded Dat Display), without "functional overlay" option.

       And in these activated buttons: light(light 0,...,light 3, with the value, 0.4, 0.0, 0.6, 0.2. and brightness: 0.35). In the option of phase Encoded Dat Display (Angle Cycles:1.0; Angle offset: 0.0)

 

       I just use File--load overlay  then choose that *.volume file to show that volume. And in the terminal there are error information:Couldn't load *.volume, Vset_read_vertex_set:MRISreadVertexposition failed.

 

      Thanks a lot for your help!

 

      Joe

have you tried changing the threshold in configure->functional overlay? What kind of values do you see?

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 thickness
by 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 regards
