Add coactivation-based parcellation algorithm, as described in Bzdok et al. (2013).

Here's a draft of my understanding of the necessary steps:

  1. For each voxel in the mask, identify studies in dataset corresponding to that voxel. Selection criteria can be either based on a distance threshold (e.g., all studies with foci within 5mm of voxel) or based on a minimum number of studies (e.g., the 50 studies reporting foci closest to the voxel).
  2. For each voxel, perform MACM (meta-analysis) using the identified studies.
  3. Correlate statistical maps between voxel MACMs to generate n_voxels X n_voxels correlation matrix.
  4. Convert correlation coefficients to correlation distance (1 - r) values.
  5. Perform clustering on correlation distance matrix.

Will compare Bzdok 2013 approach to Chase 2020.
