mne_analyze Xmsh_error_popup: "Please load the main surfaces first"

Hi Alex, Tristan and others,

my problem was indeed that I did not run this

. $MNE_ROOT/bin/mne_setup_sh

Running this did the trick. It seems at my previous institute it was
initialized automatically, so i did not think of it. Awesome. Tristan
seems to have posted it on the MNE list by now.
Thank you for your help. I really appreciate it.
I can finally move on with my data analysis.
