Dear all, I ran a script, to create my bem with the following options: mne\_setup\_bem.sh im18 --icosrc 3 --icovol 2 --bem 3 translated to oct-6, 5120 points per layer and 3 compartments It ran completely through and did not give me any visible error messages. However, the process did not create the file, I used so far for any other subject. The file I am looking for is: freesurfer/im18/bem/im18-oct-6p-src.fif Here is the screen output of this process: Running: mne\_setup\_bem.sh im18 --icosrc 3 --icovol 2 --bem 3 mne\_setup\_source\_space --subject im18 --ico -6 --cps --overwrite Setting up the source space with the following parameters: SUBJECTS\_DIR = /SCR4/charlie/imesapp/freesurfer/ Subject = im18 Surface = white Octahedron subdivision grade 6 Create a source space with patch information > > > 1.

Hi Maria, mne\_setup\_bem.sh is not a default MNE command so it's not clear to me what can go wrong. Can you try on the MNE sample data to see if the problem occurs too. If not then it's a problem with your subject otherwise I should be able to reproduce the bug and look into it. Do you hesitate to share this mne\_setup\_bem.sh script as I feel it could be useful to others. Best, Alex ---

Hi Alex, though it must sound like a stupid question: what sample data do you mean and where can I get it? About the shell-script: it is not mine and it works with a Makefile-script in the background, making it rather difficult to deciphere, what the program is supposed to do at all times. I should be able, to give you the exact mne command lines and options by tomorrow. About sharing the script itself, I have to ask, as it is not mine. Cheers, Maria ----- Urspr?ngliche Mail ----- ---

hi Maria, your problem seem to occur with only one of your subjects so forget about the sample data. Share the files with us so we can investigate. Best, Alex
