Hi FreeSurfer Developers,

I was running recon-all and it stoped at smooth1. The command is: recon-all -i T1image.nii.gz -s subject_name -all

Below is error message on the screen:

Although the message looks like the shortage of memory, it could run a few weeks ago. So, I really doubt memory is the main reason (the physical memory is 40GB)...The only difference before and after I can run is I reinstall the same version of Matlab 2016b by accident. Do you think I have to change some setting to run it?

Also, I've looked for solutions and couldn't find a one which really fits my problem. Would you please help me trouble-shoot this issue? Thank you so much.
