what is your  mri_vol2surf command line? Can you view the output in tksurfer? What is your matlab command line?

Dear Freesurfers,

I am struggling with a very basic step at the very beginning of my processing pipeline. 
This is what I've done: registered BOLD to anatomical data using bbregister, results checked with tkregister2 - all seems fine. Then I want to project BOLD data to the surfaces using mri_vol2surf - no error so far. BUT when trying to load the mri_vol2surf output into matlab (load_nifti.m) I get this error:

??? Attempted to access hdr.dim(2); index out of bounds because numel(hdr.dim)=0.
Error in ==> load_nifti_hdr at 121
if(hdr.dim(2) < 0)
Error in ==> load_nifti at 80
hdr = load_nifti_hdr(niftifile);

It seems that the hdr struct is completely empty.

Thanks in advance for any kind of help, have a nice week,

Nadine
