hi Junpeng,

I assume you work on a windows machine. To allow parallel computing  
you need to start the functions using "if \_\_name\_\_ == '\_\_main\_\_'".

Your script should look something like this:

if \_\_name\_\_ == '\_\_main\_\_':  
&nbsp;&nbsp;&nbsp;&nbsp;import mne  
&nbsp;&nbsp;&nbsp;&nbsp;mne. ...

Hi Alex,

Thank you for your quick response.  
I will try your suggetions.

May I ask you  
what is the matter with my first question:  
" ImportError: No module named surfer ".  
When I run the example code plot\_read\_forward.py,  
such error raised.

Best wishes,  
Junpeng

Hi Junpeng,

You need install the PySurfer-package, e.g.

pip install pysurfer
