The Geo Measures Plugin can carry out geometric analysis on protein structures.In addition, it makes other trajectory analyzes such as Probability Density Function (PDF), Root Mean Square Deviation (RMSD), Radius of Gyration (RG), Free Energy Landscape (FEL), Principal Component Analysis (PCA), Ramachandran map, Root Mean Square Fluctuation (RMSF), Define Secondary Structure of Proteins (DSSP), and Modevectors. Altogether there are 14 tools, which can be easily used by the graphical interface.

PyMOL version higher than 2.0.

It is highly recommended to install PyMOL using the Ananconda3 package [1].

You need to install python packages.

To do this use the command:

pip install pandas matplotlib scipy mdtraj sklearn
