Dear Asa,
Thank you very much for the interest in our thalamic atlas.
The atlas is defined as a tetrahedral mesh (not voxels) in its own average space. So there is no probabilistic map in MNI space. You could try segmenting your MNI template with FreeSurfer + the thalamic module and use that. But actually: why not simply segmenting the subjects directly? You can always register them to MNI (alone with the thalamic segmentations) if you want.
Kind regards,
Juan Eugenio Iglesias http://www.jeiglesias.com

Dear Experts,
I would really appreciate it if you could help me with this question:
I would like to use the probabilistic atlas of human thalamic nuclei; provided by Iglesias et al. (2018); as a prior knowledge to locate the LGN within my subjects (prior knowledge would be the Atlas, the functional/structural data of subjects would be available and hence, I assume I would be able to get a better estimate for the location of LGN within the subjects).
In order to do so, I need this probabilistic map to be available in the MNI or the fsaverage space.
May I ask your opinion about this approach? Do you think it is feasible to have these probabilistic atlases in the MNI/fsaverage space?
Best Regards,
Asa Farahani
