[Mne_analysis] mne_analyze Xmsh_error_popup: "Please load the main surfaces first"

[Björn Herrmann]

Hello members,

I found a problem in the list's archives which I have as well (I
copied it below). Tristan described it in detail (see below), so I
won't repeat it here (problem to open the viewer in mne_analyze). I
followed Alex's suggestion using the sample data set, but the problem
remains. I use the newest MNE version (Tristan seemed to have used an
older one) on a new Ubuntu Linux 64bit. Maybe one of you has a
solution? Currently, I cannot co-register the MRI and MEG.
Thank you for any help.

hi Tristan,

do you have the same problem when trying using the MNE sample data?

https://mne-tools.s3.amazonaws.com/datasets/MNE-sample-data-processed.tar.gz

if this works make sure your respect the layout of the anatomical
files on disk for your subjects.

Let us know how it goes.

Alex
