Dear Bruce, Thank you very much for your patient instruction! In fact, I used *"file--load overlay*", then with below error information. Maybe I can try mris_calc. Thanks again! Best regards! Joe 2010/2/2 Bruce Fischl > it looks like you are trying to load the volume

it looks like you are trying to load the volume measures as a surface, not as an overlay. Use file->load overlay. Note that you can also use mris_calc to generate the volume measures. cheers Bruce On Tue, 2 Feb 2010, keepmoon wrote: > Dear Bruce, > >This is the all information in tci:

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 bright

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 som

Hi Joe, I think we output a volume measure for the gray matter as well - we simply multiple the thickness by the surface area. cheers Bruce On Mon, 1 Feb 2010, keepmoon wrote: > Dear developer, > > I want to compare the grey matter volume by VBM to cortical thickness > by freesurfer. But i

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
