I’ve run an Amber trajectory and generated grid data as a volumetric map. The density is calculated by treating each atom as a 3-dimensional Gaussian function whose standard deviation is equal to the van der Waals radius. The format of the file is xyz (see head of the file below). 727 C 3.46464014 25.54114723 39.11305046 0.03241467 C 3.46464014 26.54114723 40.11305046 0.03353754 C 3.46464014 28.54114723 40.11305046 0.03223133 C 3.46464014 29.04114723 37.61305046 0.03259914 C 3.46464014 30.04114723 41.11305046 0.03254872 C 3.46464014 31.54114723 28.11305046 0.03995054 C 3.46464014 32.04114723 38.11305046 0.02878203 C 3.46464014 33.04114723 42.61305046 0.02801451 Is there a way to visualise in Chimera the protein together with volumetric map? Thank you in advance for any advice George
