Hi,

Then I get :

Error: mghRead(/Applications/Freesurfer/7.2.0/subjects/211025/1270_1301/mri/wm.mgz, -1): read error

Should I go through recon all process for all files I have ?

Can you perhaps tell me where I have possibly gone wrong?

I simply just used the code I always used for freeview then this happened. I’d like to avoid making same mistakes I might have made.

Thanks for your help!

It might be that the wm.mgz file is corrupted. What happens if you run
mri_info wm.mgz

Hi Bruce,

Do you mean that I should re-do the recon-all process?

I tried to re run freeview but it did not work. And Yes I think the files have been overwritten at some point which I am trying to figure out to avoid making the same mistake in the future.

However, the question is I have done the exact same process I always did to view mri files on freeview. I have set and used the same subject directory, used the same code, and etc.

Here’s the code I used:

Which gives me this:

Then, when I check mri folder, notice the selected files have been overwritten (I think) and are shown as 0 byte in size.

Can you see where I went wrong to overwrite those files?

Thank you for your help.

Best,
H

Is this for a subject that you can’t load the wm.mgz for? It doesn’t show any errors. Is the wm.mgz zero length? I don’t see how those things can both be true unless you overwrote it at some point. If you haven’t manually edited this subject maybe you should just rerun it?
