Hi,
I'm in the stable 4 environment of FreeSurfer and am getting an error
when I try to grad_unwarp a volume that comes out of unpacksdcmdir. The
rror I get is:
gradfilename is
/autofs/space/windu_006/users/grad_unwarp_bash_MartinosCenter/grad_unwarp_tables/avanto.gwv.
Loading...
Unwarp data loaded.
slice 1/128 9.1e-05
??? Error using ==> interp3
V must be a 3-D array.
Error in ==> unwarp_resample at 206
im1vec = interp3(imvol,C1,R1,S1,interp_method);
Error in ==> convert_unwarp_resample at 211
[volout, Mout] =
unwarp_resample(vol,M,size_out,Mout,Mdc,unwarpflag,jacflag,0,interp_method,inflag,thruflag,gradwarpfile);
>> ERROR: output file not created
I think the problem is the dimensions of the volume I'm trying to unwarp
are off. When I type:
mri_info flash30.mgz
I see:
type: MGH
dimensions: 256 x 256 x 128 x 8
voxel sizes: 1.0000, 1.0000, 1.3300
type: SHORT (4)
fov: 256.000
dof: 0
Any suggestions as to the best way to get around this problem?
Thanks,
Bill
