External Email - Use Caution Hello All, I am facing a problem during the coregistration process to get the -trans.fif file. I have reconstructed the anatomical data using freesurfer, used water shed algo for the bem. But when I am trying to get the -trans.fif file using mne.gui.coregistration() I am getting the below error : " mne.gui.coregistration(subject='IR1', subjects\_dir=subjects\_dir)     Triangle neighbors and vertex normals...     Triangle neighbors and vertex normals... \*\*\* Error in `python': corrupted size vs. prev\_size: 0x000055c45f5e5f10 \*\*\* ======= Backtrace: =========
