Dear MNE group

I am new to MNE and did not succeed to get things to work yet  
at the moment two things hold me:  
1. mne\_analyze open in a strange way. it is a narrow window with all the  
areas piled one over the other. there is little room to display anything  
this way (the surface of the head cannot be enlarged to cover more than  
1cm). buttons also seem not to be displayed as meant to. I can however load  
and display headshape + MRI and realign. I am running ubutnu Pangolin  
64bit. did anyone encountered such a problem?  
2. I work on 4D data after conversion to fif (thanks, Denis). after running  
freesurfer I align the MRI to the digitized headshape with mne\_analyze and  
save MRI set and the transformation matrix. I then follow this pipeline:

mne\_watershed\_bem --atlas  
mne\_setup\_source\_space --ico -6 --overwrite  
mne\_setup\_forward\_model --homog --surf --ico 4  
mne\_do\_forward\_solution --spacing oct-6 mindist --overwrite  
--meas 'subject1.fif' --megonly  
I get the following message:

I found a similar report here:  
[https://mail.nmr.mgh.harvard.edu/pipermail//mne\_analysis/2012-April/001003.html](https://mail.nmr.mgh.harvard.edu/pipermail//mne_analysis/2012-April/001003.html)  
but I did not see a solution there.

Thanks  
Yuval

how did you setup MNE?

did you actually source mne\_setup\_sh as explain on the website? or did you  
manually set your PATH ?

you should do something like:

export MNE\_ROOT=..  
source $MNE\_ROOT/bin/mne\_setup\_sh

at least if you use bash.

how did you convert the 4d file? python or the mne C command?

maybe Denis can help you on this.
