XCrySDen is a crystalline and molecular structure visualisation program aiming at display of isosurfaces and contours, which can be superimposed on crystalline structures and interactively rotated and manipulated. 

Using  xcrysden

xcrysden is coming in two versions, one for GPU-nodes like max-display.desy.de, the other one for plain login nodes without GPU. Both can be used with modules:

# Using the GPU-capable version
[max]% module load maxwell xcrysden #  this is identical to module load maxwell xcrysden/1.6.2-nomesa
[max]% xcrysden

# Using the non-GPU version
[max]% module load maxwell xcrysden/1.6.2-mesa
[max]% xcrysden
