nilearn.connectome: Functional Connectivity#

Tools for computing functional connectivity matrices and also implementation of algorithm for sparse multi subjects learning of Gaussian graphical models.


ConnectivityMeasure([cov_estimator, kind, ...])

A class that computes different kinds of functional connectivity matrices.

GroupSparseCovariance([alpha, tol, ...])

Covariance and precision matrix estimator.

GroupSparseCovarianceCV([alphas, ...])

Sparse inverse covariance w/ cross-validated choice of the parameter.


sym_matrix_to_vec(symmetric[, discard_diagonal])

Return the flattened lower triangular part of an array.

vec_to_sym_matrix(vec[, diagonal])

Return the symmetric matrix given its flattened lower triangular part.

group_sparse_covariance(subjects, alpha[, ...])

Compute sparse precision matrices and covariance matrices.


Return correlation matrix for a given covariance matrix.


Return partial correlation matrix for a given precision matrix.
