[Mne_analysis] mne make_scalp_surfaces error

[Leonardo Barbosa]

Thank you for the feedback.

I admit that the download page for the MNE-C is a bit confusing.
On the top there is the old version 2.7.0, followed by the nightly-build
2.7.4, followed by the last stable version 2.7.3.

I tried the 2.7.3, which I guess is the last stable version (from 2011),
and got the same error.

I installed the nightly-build (2016), and now it is working, although I'm
not very comfortable running nightly-builds in production...

Also, it complained about a missing library:  libgfortran.so.1

*mne_surf2bem: error while loading shared libraries: libgfortran.so.1:
cannot open shared object file: No such file or directory*

Which is weird, since it is an old lib, and I have  libgfortran.so.3
installed, and the previous MNE versions seemed to do just fine.
I added an old  libgfortran.so.1 available in the anaconda repository, but
since I added the whole folder to the ld.so.conf, I'm getting some weird
warnings...
I think I'm going back to MNE-2.7.3-3268-Linux-x86_64 after I finish
generating the surfaces, and remove libgfortran.so.1 from the path

Is there a stable version of 2.7.4 ?

Thank you,
Leonardo
