Hi all, The RCSB made a change to their web site this morning that broke the fetching of PDB files by ID code in Chimera. We have committed a fix to Chimera that re-enables PDB fetching, and that fix will be in tomorrow's daily build. Note that this problem only really affects you if you are trying to access PDB files you've never used before, because Chimera caches fetched PDB files on your machine. We hope to make a production release that incorporates this fix sooner rather than later, but aren't yet sure exactly when that will be. --Eric Eric Pettersen UCSF Computer Graphics Lab
