Can you try these two commands?

1. freeview /mnt/data_analysis/freesurfer_data/diffusion_recons/sub01/mri/wmparc2diff.mgz

2. mri_info /mnt/data_analysis/freesurfer_data/diffusion_recons/sub01/mri/wmparc2diff.mgz

Dear Yujing,

 

Thank you for your prompt reply. Yes, it exists.

 

$ ls -l /mnt/data_analysis/freesurfer_data/diffusion_recons/sub01/mri/wmparc2diff.mgz
-rwxrwxrwx 1 root root 65906 Jan 31 18:00 /mnt/data_analysis/freesurfer_data/diffusion_recons/sub01/mri/wmparc2diff.mgz

 

But while loading manually it is not detected. Also, I used the "all types" option, but same issue.

 

Thanks

Ramesh

Can you check if the volume exists?

ls -l /mnt/data_analysis/freesurfer_data/diffusion_recons/sub01/mri/wmparc2diff.mgz

 

I only see wmparc.mgz in your listed directory.

Sorry, I forgot to attach the files with the earlier message.

 

Dear Expert,

 

I am finding an error in loading wmparc2diff.mgz in freeview. The error report from the terminal is;

 

$ freeview -v lowb.nii.gz $SUBJECTS_DIR/$subj/mri/wmparc2diff.mgz:colormap=lut -f $SUBJECTS_DIR/$subj/surf/lh.white:edgecolor=green $SUBJECTS_DIR/$subj/surf/rh.white:edgecolor=green -viewport coronal
error: mghRead(/mnt/data_analysis/freesurfer_data/diffusion_recons/sub01/mri/wmparc2diff.mgz, -1): could not open file
MRIread failed: Unable to read from /mnt/data_analysis/freesurfer_data/diffusion_recons/sub01/mri/wmparc2diff.mgz

 

In the attached Error-1 file it shows error after entering the command in the terminal.

Error-2 file - trying to load the file manually. You cannot see the wmparc2diff.mgz file though it is created and located in the folder.

 

Please see the attached files and give your suggestions.

 

Regards

Ramesh
