Looking at the daily builds, it seems like md cluster might do the trick, if the set of structures is opened as a trajectory - it is not exactly clear to me how to do that though, for a set of individual PDB files as opposed to an MD trajectory or NMR multi-model ensemble.

Also, the PDBs generated by alphafold are in arbitrary orientations. Is there a way to open, align and cluster a large set (100s) of structures in arbitrary orientations?

Hi,

Are there any tools in ChimeraX suitable for clustering/analyzing conformational ensembles, e.g. as generated by AFSAMPLE2 (https://www.nature.com/articles/s42003-025-07791-9) or similar approaches?

The closest I could find was this:


The similarstructures interface looks great, but it seems like this can only analyze sets of structures generated in the tool - is there any way to use it to analyze an arbitrary set of structures?

Basically I would like a way to (for a set of say 200 input structures of the same sequence) quickly align them and then cluster them, to identify and group representative conformational states in the ensemble of predictions.
