MNE Experts,
Our group is working with some old MEG data from 2012. Just started a week or so ago with MNE software and I'm having issues exporting the dSPM source reconstruction to an .mgz (or .nii) file. Also, after that has been solved, if one can only export the dSPM data to an .mgz/mgh file, is there a command for converting to .nii format? Very new to this, I appreciate your help.
Thank you,
Franklin

The dspm source reconstruction is 4 dimensional data on a surface.
While technically there is some support for this in the mgz format it
is not well optimized for MEG source reconstructions, and it is
therefore not supported to convert (so far as I know). Additionally
there is no support for surfaces in nifti (though there is the gifti
format, but I don't know if giftis can support time data in them). We
can probably help you much better if you tell us what you want to do
with the source reconstructions. All of the MNE formats (stc is
probably what you are talking about here) are fully readable by both
MATLAB and python, so we should be able to help you take the next step
with your analysis.

Hi Franklin,
Please keep the list cced so everyone can follow. Well, the MNE matlab
toolbox included can read in the STCs. From there you should be able
to run an ICA on that data fairly easily. I'm not familiar with either
GIFT or GICA, so it will be hard for me to point you in the right
direction there (though if anyone here has a suggestion please chip
in). Otherwise, you can describe to their mailing list the data that
you have (i.e. a matrix in matlab of sources x time (with the sources
being located on a cortical surface)) and see if they can help with
the next step.
HTH,

Hi D,
Right, I've done an export to stc from mne_make_movie and then opened it up using the matlab package. Thank you for the suggestions.
