Hi Chara,  The version of Chimera you are using is quite old and it can no longer reach HTTPS web services (like the "align chain sequences" web service) because its SSL implementation is out of date. Please upgrade to the current version of Chimera and things will work. --Eric Eric Pettersen UCSF Computer Graphics Lab

Dear all,

After performing the structure comparison of 2 structures using the "MatchMaker" tool of the chimera software, I need to run an alignment of the structure sequences using the "align chain sequences" tool of the chimera.

Unfortunately, I am getting the following error message in the reply log that persists for weeks:

Typically, if you get a TypeError, it's a problem on the remote server and it should be fixed shortly. If you get a different error or get TypeError consistently for more than a day, please report the problem using the Report a Bug... entry in the Help menu. Please include the traceback printed above as part of the problem description.
