With Compute Metrics access statistical properties of the volume field.

Enter a Result File Name (*.gdr) to save the results in. Then, select on which of the loaded Volume Fields the properties should be computed. The Random Seed influences the results of Autocorrelation and Correlation Length.

Below, choose which metrics should be computed.

Minimum, Maximum and Mean Values, Standard Deviation and Variance can be computed for either Pore, Solid, All Materials, Chosen Materials or Chosen Material IDs.

Minimal, Maximal and Mean Values can also be determined slice-wise for a chosen direction and Pore, Solid, All Materials, Chosen Materials or Chosen Material IDs.

Additionally, you can compute the Sum or Mean Value Along Axis for a chosen direction and Pore, Solid, All Materials, Chosen Materials or Chosen Material IDs.

When Autocorrelation is selected, the similarity of voxels in a given distance between Minimal Length Scale and Maximal Length Scale is measured. This is similar to the MatDict command 2-Point Correlation.

The Correlation Length is a measure on which length scale the values of the volume field change.

With Spatial Intensity Histogram a histogram of the values in the volume field is computed with respect to the entered Number of Bins.

Clicking Run computes the chosen metrics. After the run is finished, the result viewer opens and shows the results in the report tab. Additional plots are available in the Plots subtab if Slice Minimal, Maximal and Mean Value, Sum or Mean Value Along Axis, Autocorrelation, or Spatial Intensity Histogram are selected.
