3.2.29 Compute Noise Correlation

<compute_corr_matrix></compute_corr_matrix>

  • on
  • off Default Setting

This is only active if <write_interpolated_variance> is set to on. Default value is set to off, as this function has had mixed results. The interpolated noise variance is still written out, using a heuristically determined noise correlation matrix. See Irfanoglu, M.O., L. Walker, Machiraju, R., and Pierpaoli, C. (2011). Accounting for changes in signal variance in diffusion weighted images following interpolation for motion and distortion correction.
