Depending on the choices in the settings dialog the size distribution of pores can also be visualized through the Pore Size Visualization tab.

Pore Geometries as *.gdt Files

If Write Pore Geometries as *.gdt Files was checked, you can load a structure for each bin into the visualization area. Select the *.gdt file corresponding to a particular pore diameter from the drop down menu and then click Load Pore Geometry (*.gdt).

In this example, a bin size of 2 voxels (800 nm) was chosen. The Pores_Diam_008.00_Voxels.gdt file shows the pore space separated into two Material IDs. Pore voxels which belong to pores with a diameter of 8 voxels (or more) are assigned to Material ID 04, while the pore voxels of smaller pores are assigned to ID 00 (invisible). The Pores_Diam_016.00_Voxels.gdt file shows the more limited pore space in which spheres with a (larger) diameter of at least 16 voxels would fit. The Pores_Diam_020.00_Voxels.gdt file shows that in this structure, the pore space in which spheres with diameter over 20 voxels can fit is very small.

Check or un-check visible in Settings → Color & Visibility Settings, to turn off the visibility of the solid materials in the structure (Material ID 01, Material ID 02, and Material ID 03) and see only the pore space filled with water (Material ID 04).

Pore Size Distribution

If Write Pore Size Distribution as *.gsd File was checked, you can click on Load GeoDict Size Distribution (*.gsd) to load a volume field containing the pore diameters.

The value at each voxel is the diameter of the largest sphere, that contains this voxel and fits inside the pore space. Thus, the diameter for the solid materials is zero (dark blue in the picture below). Comparing the volume field shown below with the pores, that have a diameter of 20 voxels or more, you can see that these pores have a red color in the volume field plot.
