External Email - Use Caution
Hello,
I ran a successful dt_recon and then wanted to use
mri_vol2vol --mov $subj_dir/dtrecons/${subj}.${cond}/lowb.nii.gz --targ $subj_dir/diffusion_recons/${subj}.${cond}/mri/aparc+aseg.mgz --inv --interp nearest --o $subj_dir/dtrecons/${subj}.${cond}/aparc+aseg2diff.nii.gz --reg $subj_dir/dtrecon/${subj}.${cond}/register.dat --no-save-reg
to get the anatomical segmentations into diffusion space. However, when running the above code I get the following error message?
echo subj = AES139 , cond = Rest
subj = AES139 , cond = Rest
set echo
cd /Volumes/DANIEL/dti_freesurf
mri_vol2vol --mov /Volumes/DANIEL/dti_freesurf/dtrecons/AES139.Rest/lowb.nii.gz --targ /Volumes/DANIEL/dti_freesurf/diffusion_recons/AES139.Rest/mri/aparc+aseg.mgz --inv --interp nearest --o /Volumes/DANIEL/dti_freesurf/dtrecons/AES139.Rest/aparc+aseg2diff.nii.gz --reg /Volumes/DANIEL/dti_freesurf/dtrecon/AES139.Rest/register.dat --no-save-reg
regio_read_register(): No such file or directory
Could not open /Volumes/DANIEL/dti_freesurf/dtrecon/AES139.Rest/register.dat
Matrix from regfile:
MatrixPrint: mat = NULL!
No such file or directory
I have attached an example register.dat file in case that is the issue.
also the output for ls -l register.dat
-rwxrwxrwx 1 administrator staff 323 Feb 18 13:59 register.dat
Any advice with troubleshooting is greatly appreciated!
