Dear SPMers,

We have acquired SPGR images in bruker format and
coverted to analyze using pvconv.pl perl script by
Matthew Brett. When i display the converted image in
SPM it looks absolutely fine. But when i try to
extract the 3D brain surface using render - xtract
brain ... i get the following error.

SPM2: spm_surf (v2.3)
17:10:24 - 02/12/2004
 =======================================================================
??? Error using ==> *
Inner matrix dimensions must agree.

Error in ==> C:\MATLAB6p5\toolbox\spm2\spm_surf.m
(do_it)
On line 106  ==>        vertices = (Mat*[vertices' ;
ones(1,size(vertices,1))])';

Error in ==> C:\MATLAB6p5\toolbox\spm2\spm_surf.m
On line 53  ==> do_it(P,mode);

Error in ==> C:\MATLAB6p5\toolbox\spm2\spm.m
On line 1276  ==> evalin('base',CBs{v-1})

Any insights is greatly appreciated
Thanks
