Deprecation of ligand model coordinates in SDF format starting Dec 10

09/17

Starting December 10, 2024, RCSB PDB will no longer serve ligand model coordinates in MOL2 or SDF format. These files are currently served under https://files.rcsb.org/ligands/download/< ccd_id >_model.mol2 and https://files.rcsb.org/ligands/download/< ccd_id >_model.sdf.

Model and ideal coordinates for chemical components in CIF format will continue to be available from https://files.rcsb.org/ligands/download/< ccd_id >.cif.

Programmatic access should be updated as needed.

Ligand data files for ideal coordinates will continue to be served in SDF formats under https://files.rcsb.org/ligands/download/< ccd_id >_ideal.sdf.

Information about all files available for download from RCSB PDB is available.

Programmatic access should be updated to access model coordinates in CIF format
