Hello all,

> From mne\_read\_epoch I get data that is channels by time by epochs and

would like to convert that into source information using an inverse  
operator, so I can turn the data into an stc file and have it ready for  
label processing.

Is there an m file to use, or some other way of computing the information  
using the channel based data and the inverse operator in matlab?

Thank you,  
-Ricky

Hi Ricky,  
&nbsp;&nbsp;I think you're looking for mne\_ex\_compute\_inverse.m which you many need  
to modify and mne\_write\_inverse\_sol\_stc.m

Regards,  
Hari

Hi Ricky,

if you turn out to write a new MNE function for your needs, it would  
be great if you could share it with the community.  
I'd be happy to add it to the mne-matlab toolbox:

[https://github.com/mne-tools/mne-matlab](https://github.com/mne-tools/mne-matlab)

By sharing your code you help others but others help you too by  
suggesting improvement and eventually fixing bugs you did not see.

Best,  
Alex
