Hi
I was using phenix.autoMR and when it tried to go on to autobuild the job ended with the following error message

AutoBuild Input failed
can only concatenate list (not "str") to list

There are two molecules in the asymmetric unit.  I tried running phenix.autobuild with the output pdb from molecular replacement and got the same message.  The file looks OK to me though.
Can you tell me what the problem is?
Regards
Christine
