How to download the template brain of a statistical map on NeuroVault?

I am trying to use a biomarker from this collection on NeuroVault: Decoding Activity in Broca's Area Predicts the Occurrence of Auditory Hallucinations Across Subjects. I’d like to be able to register my participant data to the same space that the biomarker is registered to, but I cannot figure out which template they’re using (the associated paper says MNI space, but doesn’t specify a specific template, e.g., MNI152NLin2009cAsym or something similar).

Does NeuroVault have an option to directly download the brain that the map is registered to? Or is there another way to access that information? Any help would be most appreciated! Thank you!

Hi @Maya_Sanghvi and welcome to neurostars!

I believe NeuroVault uses the FSL default MNI space (MNI152NLin6Asym). You can get that distributed with FSL or on templateflow (https://github.com/templateflow/tpl-MNI152NLin6Asym/tree/c906e8d808a34719e5024a4bde61f03a4e411ddd).

Best,

Thank you for the quick and helpful response, Steven! It seems like people are also able to use their own structural brain as the reference image for the map they upload. (The reason I’m not sure that it’s MNI152NLin6Asym is because when I download the map and try to view it on an MNI brain the biomarker looks shifted compared to the NeuroVault viewer.) Is there any way to know for sure that they used the default MNI space, or to download the template they used from NeuroVault if different?

Thanks again!

Hi @Maya_Sanghvi,

Hmm, I am not sure that’s an option in neurovault, but this FAQ entry might help with apparent misalignment? https://neurovault.org/FAQ

Looking at the supplementary information for the paper associated with the collection they mention that preprocessing was done using BrainVoyager. BrainVoyager uses MNI-ICBM 152 2009c as its default MNI template:

No guarantee that’s what Fovet et al used, but may be worth looking at.

Thanks for the help! I think it might have been a cropping issue (i.e., maybe NeuroVault or the authors cropped the weight mask to save space or something), so I’ve tried padding the mask with zeros and it looks a bit better. Thank you for the BV template, I’ll try that as well!
