[Mne_analysis] mne_analyze question

[Franklin Lovell Orndorff-Plunkett]

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.

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,
D

Then the hope is to take each of these sets of ICs and average across subjects (maybe GICA is better suited, it's still unclear) then export those ICs to matlab format.  The final analysis is a discrete wavelet transform of those (group or averaged) ICs and then statistical characterization in wavelet space to differentiate between the hallucinating and normal signaling.  We're using the MIALab software for the ICA portion (GIFT/GICA) and they require a nifti format.
