Hello! I'm trying to run a homology model on a protein sequence using BLAST, but my Blast: query window shows up empty. At first I got this error in the reply log: File "C:\Program Files\Chimera 1.15\share\blastpdb\pdbinfo.py", line 151, in fetch_pdb_info import replyobj ImportError: No module named replyobj I solved it by changing the code to "from python import replyobj". Now I can actually see what the error is. A few more functions are called until we get to this: File "C:\Program Files\Chimera 1.15\bin\lib\socket.py", line 480, in readline data = self._sock.recv(self._rbufsize) error: [Errno 10054] An existing connection was forcibly closed by the remote host I've allowed chimera through the firewall and I have a modeller license key, I believe I've entered it somewhere in Chimera at some point. Any ideas what might be causing this? Thanks for any advice, Stefan Dobrev
