On Big Sur you will need to grant permissions to read and write for all the freesurfer binaries. Have you done so? Also, you can download the latest standalone build of freeview for macOS here: https://surfer.nmr.mgh.harvard.edu/fswiki/UpdateFreeview

External Email - Use Caution

Hello,

I have recently changed from Linux to Mac OS (Big Sur) and have problems with loading lh.pial and rh.pial files on the Mac system. The files were created using the recon-all command on the Linux system, this finished without error. But I wonder if there is some problem going from Linux to Mac regarding these surface files.

For example, I can load these files on the Linux, but when trying to load the surfaces on the Mac in Freeview either manually or via the command line the following error is repeatedly printed in the terminal:

error: freadFloat: fread failed error: Invalid argument

Further, commands such as mris_convert lh.pial lh.pial.asc work on the Linux system but crash and give the same error as above on the Mac.

Both systems are running Freesurfer 7.1.1 (freesurfer-darwin-macOS-7.1.1-20200811-8b40551 / Freesurfer-linux-centos7_x86_64-7.1.1-20200723-8b40551)

Thanks in advance for your help,
