Sarang, Tzvetan and others at Konstanz have an enhancement request. (I discussed this in the FT meeting today, but elaborating here). Some users who use FT for most of the pipeline prefer to use the Nutmeg GUI for easier use of clicking/marking the fiducials and/or for the computation that is computed for alligning Polhemus-marked (or otherwise obtained) electrode positions to the MRI skin surface, and then bringing this allignment into mri.transform, and continuing with analysis in FT from there onwards. Robert suggested that I make a short 2 min video of a demo of this coreg (including audio and the screen). I will ask JM for help on his Mac for this... Sarang has suggested that this be formally incorporated into FT, rather than FT calling NM as an external software. It depends on the SPM MRI viewer. Or could be brought in as a 'nutmeg-lite' into fieldtrip/external/nutmeg. Either way, a separate download of Nutmeg would not be required by the user. A snippet of code, provided by Tzvetan, for after the coreg is done in Nutmeg is as follows: global nuts st mriR=ft_read_mri('yourMRI'); % apply transformation matrix and plot to verify mriR.transform=inv(nuts.coreg.meg2mri_tfm)*st.vols{1}.mat; cfg=[]; cfg.interactive='yes'; figure; ft_sourceplot(cfg, mriR);
