The NeuroVault database (https://neurovault.org/) is a:
place where researchers can publicly store and share unthresholded statistical maps, parcellations, and atlases produced by MRI and PET studies.
This allows researchers to compare results from multiple studies.
The NeuroVault API (https://neurovault.org/api-docs) allows users to access this data with some calls to a RESTful API.
neurovault package wraps these commands using
httr. Here we will look
library(neurovault) res = nv_collection_images(id = 77) df = results_to_df(res$content$results) head(df)
We can download and view a labeled atlas for the results:
library(neurobase) res = download_nv_atlas(id = 1408) atlas = readnii(res$outfile) ortho2(atlas)
You can access the neuroimaging data model (NIDM) (http://nidm.nidash.org/) information using:
nidm = nv_nidm_results()
