Volume-normalised shapes of primitive cells. This plot embeds every PDB cell so that similar shapes sit together, using Selling-closure distances between nearby settings. Symmetry fixes edges and angles, and those constraints straddle the familiar unit-cell shapes.

Volume-normalised linear key

The checkboxes decide which cells are drawn. Colour only paints them. Then either pick one cell, or lasso a region and take those PDB ids elsewhere.

Paints the cells that remain. It does not hide any.

Selection

Drag to turn the cell. Scroll to zoom. Double-click to reset. The table holds the true edges; turning the picture foreshortens them.

Drag a loop around the cells you want. Unticked systems and centrings are left out.
