There is code for that in spm_eeg_inv_forward. It's not visible from the GUI but it works (albeit slowly). In SPM12b in headmodelling batch you can input your own meshes for the head model. Sensor locations should be go through the normal SPM route. Another possibility if you manage to get the same mesh in Brainstorm and SPM you can compute lead fields in Brainstorm and then just replace the ones that SPM computes (in SPM_gainmatrix... file). I don't have much experience with Brainstorm so can't give you more precise instructions on that side of things. Best, Vladimir > > Thank you, > > Octavian
