Hi,
I'm trying to paint functional data onto a cortical "midgray" surface.
The surface was generated using mris_expand to expand the WM surface to
50% of the pial surface.
The data I want to paint onto this surface is in a 96 x 96 x 17 x 512
dimension NIFTI file generated using the feat command (the volume is the
resulting "filtered_func_data.nii.gz"). When using this command:
mri_vol2surf --mov filtered_func_data.nii.gz \
--reg register.dat \
--hemi rh \
--surf midgray.05 \
--nvox NonZero_voxels.txt \
--out Total_TimeSeries_RHsurface.nii.gz
I get the following error message:
NIFTI FORMAT WARNING: ncols 65938 in input exceeds 32768.
So I'm going to put the true ncols in glmin and set dim[1]=-1.
This should be ok within FreeSurfer, but you will not be
able to use this volume with other software.
And an output volume with dimensions 65938 x 1 x 2 x 512 which does not
work with FSL commands.
This is a problem since the next thing I want to do is to use fslmaths to
collapse the surface in the X, Y, and Z dimensions to obtain a mean for
the surface.
Also confusing is the fact that the above command works fine for the left
hemisphere.
What's going on? Am I doing something wrong?
