6VSJ.cif​

[UMA.SHEKHAWAT@…]

Added by email2trac

[Eric Pettersen]

In 1.3, the error is as in the ticket, in 1.4 and newer it is "mmCIF parsing error: PDBx/mmCIF styling lost near line 2897".

[Greg Couch]

Please redownload 6vsj from the PDB. You can do a "open 6vsj ignoreCache true" to get the newer version if this is your currently cached version. And we recommend updating to ChimeraX 1.4.

This bug is due to ChimeraX taking advantage of the fixed width columns in the atom_site table that the PDB provides, aka, PDBx/mmCIF styling. That speeds up the reading of mmCIF files by 2.8+ times. Somehow that spacing was lost in your version, but the file still looks like it came from the PDB (no one else puts the audit_conform table in the mmCIF files unless there are fixed width columns).
