Hello, can't find a way to do this. Found an old thread that talks about  
"updated MixedSourceEstimate.export\_volumes\_to\_nifti to include an option  
to export the surface activations as well" at  
[https://github.com/mne-tools/mne-python/pull/1462](https://github.com/mne-tools/mne-python/pull/1462) . However, I can't find  
documentation on using it, and it doesn't work if I try to use it  
(AttributeError:  
'MixedSourceEstimate' object has no attribute 'export\_volumes\_to\_nifti').  
Any help would be appreciated. Thanks, Lori

Dear Lori,

presently in MNE there is no function to export a surface activation  
to a volume.

mri\_surf2vol in freesurfer would be my approach but it would need  
the high resolution activation as input.

please open an issue at : [https://github.com/mne-tools/mne-python/issues](https://github.com/mne-tools/mne-python/issues)

so you know when we implement this.

Best,  
Alex

In the meantime, the code necessary to put a surface source estimate into a  
NIfTI volume is in a work-in-progress pull request here:

Thank you for the replies. I previously figured out a (cumbersome) way of  
getting a surface from stc into nifti, but really need a way to get the  
mixed source space in. I will keep working on it. Best, Lori
