Hi, This has happened quite some times in the last few months. I realized just now that I could not access https://www.cgl.ucsf.edu/chimerax/docs/devel/modules/core/logger.html. I then checked the following, and all were not working. Is this my own problem or a server-side issue? Is there an offline developer documentation (PDF or HTML)? https://www.cgl.ucsf.edu/chimerax/docs/user/commands/log.html https://www.cgl.ucsf.edu/chimerax/download.html https://www.cgl.ucsf.edu/chimerax/docs/licensing.html Many thanks, Roden -- This message and its contents, including attachments are intended solely for the original recipient.
