Tools for performing PCA, found in Tools/. Note: some related tools are also found in the network models section (enm).
Compute the covariance and subspace overlaps between either ENM results or PCA results (or any combination). The covariance overlap was defined in Hess, Phys. Rev. E, 65, 031910, 2002
Computes the SVD/PCA for a trajectory. This differs from the svd below in that it uses single precision math and it computes fewer right singular vectors (e.g. if your structure has N atoms and you have T timestemps in the trajectory, then the RSV matrix will be T x 3N as opposed to T x T in the svd tool). See also svd.
Performs principal component analysis for a trajectory using singular value decomposition, writing out the eigenvalues, left singular vectors (eigenvectors) and the right singular vectors (projection timeseries) as OCTAVE-formatted text files.
