Hi all, The RCSB switching off http access and only allowing https (which had been announced) unfortunately broke the fetching of PDB info associated with BLAST results, basically breaking the BLAST tools in both Chimera and ChimeraX. Fixes have been applied and will be available in tomorrow's daily builds. For ChimeraX, also available in the 1.2.3 release candidate -- hopefully also out tomorrow. --Eric Eric Pettersen UCSF Computer Graphics Lab
