Hi,
I want to register an atlas and need to determine what atlasType it is.
Based on the definition of the instances/atlasType/deterministicAtlas.jsonld and the instances/atlasType/probabilisticAtlas.jsonld, I understand it such that these are the two alternatives.
And if that is the case, when would I use instances/atlasType/parcellationScheme.jsonld?
The way I understand the definition of parcellationScheme, it would be applicable to all atlases, have I understood it correctly?
In advance, thank you for considering this question.
Addendum:
These descriptions and examples of probabilistic and deterministic atlas labels are used in this publication: Amunts, Katrin, et al. "Interoperable atlases of the human brain." Neuroimage 99 (2014): 525-532.
Maybe they could be used as inspiration for filling in the description.
"The labeling of any given location may be either probabilistic (in which each location is assigned a probability for each of the different labels in the respective map) or deterministic (in which the mapping attributes to each location one and only one label, i.e., one label has probability one whereas the probability for all other labels is zero). Probabilistic labels are particularly common in population-based mapping where they denote, e.g. the percentage of subjects featuring a particular characteristic at any given location. In turn, deterministic atlases may be derived from parcellations in a single brain (e.g. by labeling anatomical features) or as the result of a hard parcellation from probabilistic atlases (e.g., by computing maximum probability maps)."
