ERROR when trying to import anatomy folder

1

Hello, we are using brainstorm and trying to import an anatomy folder.
when choosing "import anatomy folder" --> selecting the freesurfer data folder --> hitting "Open",
we get the following error:
"MRI file was not found: T1.mgz
Surface file was not found: lh.pial
Surface file was not found: rh.pial"
Can you please help us understand what is the problem and how it can be solved?
Thank you!

Hi @SaarK
The error suggests that some key FreeSurfer output files are missing from your anatomy folder—specifically:

  • T1.mgz (MRI volume)
  • lh.pial and rh.pial (left and right pial surface files)

This usually means that the FreeSurfer reconstruction was either incomplete or not run properly. Please ensure that the recon-all process is completed successfully on your subject.

Also, you're using a very old version of Brainstorm (Feb 2020). We highly recommend updating to the latest version, as it includes many important bug fixes and improvements.
