[p_spin, r_dist] = spin_test(map1, map2, varargin)

Spin permutation (author: @saratheriver)

  • map1 (double array) – One of two map to be correlated

  • map2 (double array) – The other map to be correlated

Name/value pairs:
  • surface_name (string, optional) – Surface name {‘fsa5’, ‘fsa5_with_sctx’}. Use ‘fsa5’ for Conte69. Default is ‘fsa5’.

  • parcellation_name (string, optional) – Parcellation name {‘aparc’, ‘aparc_aseg’}. Default is ‘aparc’.

  • n_rot (int, optional) – Number of spin rotations. Default is 100.

  • type (string, optional) – Correlation type {‘pearson’, ‘spearman’}. Default is ‘pearson’.

  • ventricles (string, optional) – Whether ventricles are present in map1, map2. Only used when parcellation_name is 'aparc_aseg'. Default is ‘False’ (other option is ‘True’)

  • p_spin (double) – Permutation p-value

  • r_dist (double array) - Null correlations, size = [n_rot*2 x 1].
