No GUI PyMOL – computing distances for thousands of PDB files from Rosetta

Summary We run a script to compute the distance between 2 atoms in a series of PDB files with identical molecules in different conformations and save the distance results into a plain text file. No GUI PyMOL In previous posts I explained how we can use PyMOL as a command-line tool from a Terminal when …

Python NumPy 2.0 incompatibilities

Summary The new Numpy 2.0 is not compatible with many other packages, as I discovered after many lost hours. The final Docker images can be downloaded from alleleanalyzer. NumPy in a Docker I was interested to implement a process involving Python packages from a paper published in 2019: “AlleleAnalyzer: a tool for personalized and allele-specific …

PyMOL and Biological Units from REMARK 350

Summary Compute biological assembly from coordinates with a python script. Symmetry X-ray crystallography solved the mathematical problem to provide 3D (cartesian) coordinates but the resulting “asymmetric unit cell” does not necessarily represent the biological structure. The Protein Data Bank (PDB) now provides options to download the biological entity, which can contain a lesser number than …
