fmri spatial prior

Hi folks,

seems i used to see some documentation for how to use an

fmri spatial prior as a weighted constraint for the mne source

modelling tools. Is such functionality available in the current version ?

thank you

Hi Greg,

the python code does not implement fMRI weighting.

that's what we have in the MNE-C doc:

http://martinos.org/mne/stable/manual/source_localization/inverse.html?highlight=fmri#fmri-guided-estimates

quote:

"It turns out that the fMRI weighting has a strong influence on the
MNE but the noise-normalized estimates are much less affected by it."

as we recommend to use the noise-normalized estimates it has so far
not been requested.

Hi Alex,

So this functionality is still available in the c version ?

we have a very interesting measure derived from fMRI data

that we would like to establish the correspondence with electrical

activity source localized over frequency bands. We are submitting a grant

application with this as one of the aims. We have a very good research electrophysiologist

in our group. The data we will be working with is simultaneously acquired eeg/fmri

from UCL and possibly another site. Would there possibly be interest in collaborating to

implement something sensible ?

Best & thanks

Greg

If you open an issue on the MNE-Python issue tracker and mention these use
cases, it's possible that someone will find time to do it.
