Did you know... Cif keepinmemory The cif_keepinmemory setting is an experimental feature. When loading a CIF file with cif_keepinmemory=on, then the parsed file is kept in memory and made accessible like a dictionary from the Python API. New in PyMOL 1.7.8 Examples import pymol pymol.cmd.set("cif_keepinmemory") pymol.cmd.fetch("1ubq", type="cif") citation_titles = pymol.querying.cif_get_array("1ubq", "_citation.title") import pprint pprint.pprint(citation_titles) Output: ['Structure of ubiquitin refined at 1.8 A resolution.', 'Comparison of the Three-Dimensional Structures of Human, Yeast, and Oat Ubiquitin', 'Three-Dimensional Structure of Ubiquitin at 2.8 Angstroms Resolution', 'Crystallization and Preliminary X-Ray Investigation of Ubiquitin, a Non-Histone Chromosomal Protein', 'Molecular Conservation of 74 Amino Acid Sequence of Ubiquitin between Cattle and Man']
