Implement Analysis of Brain Coordinates CBMA algorithm
Analysis of Brain Coordinates (ABC) is a new CBMA algorithm proposed in Tench et al. (2022).
Replication data are available at https://rdmc.nottingham.ac.uk/handle/internal/9171 and https://rdmc.nottingham.ac.uk/handle/internal/9121.
I'll try to describe the method as I understand it (this comment will be edited over time whenever I have a chance to read through the paper).
- Calculate the smallest sphere that encompasses some number (k) of the nearest coordinates from different studies, for each coordinate. So for coordinate i, you would have a volume, dVi, describing that coordinate's sphere.
- It seems like k (the number of independent studies to require for each coordinate) is a key parameter.
- The minimum possible k value is 4. The number must be kept small because "the density estimate is only valid for small volumes to meet anatomical constraints."
There's a C implementation under a GPL license packaged with the NeuRoi toolbox.
Apparently they renamed the method from "coordinate density analysis" to "analysis of brain coordinates."
