I wonder if there is anyone else experiencing a VERY VERY slow opening of the phenix GUI for the latest version of 1.7.2? We have RHEL 5.3 and CentOS 5.6, both machines show this. Most of the time, it will take minutes, sometime more than 10 minutes. There is no any warning or error message, after the long waiting the GUI will suddenly show up.
There are several reasons why this might happen, most of which involve the networking configuration on your systems (including NFS). I haven't had much luck figuring out the exact cause(s), since I rarely have direct access to the computers that have these problems - in one of the few cases where I did, it had no network access and was locking up attempting to load the wxPython module (which shouldn't use any networking at all!). A couple of suggestions to try: 1. Type 'phenix' and hit enter, wait a few seconds, then enter control-C, which should cancel it - then send me whatever it prints out (it should by a Python traceback). 2. Set the environment variable PYTHONVERBOSE to 1, then type 'phenix' and hit enter, and send me the last 10-20 lines of terminal output. (There will probably be several terminal screens worth of output but I just need to see where it stops.) The more aggressive debugging approach involves adding print statements throughout $PHENIX/phenix/wxGUI2/App.py, but I'm hoping one or both of the above methods tells us something.
In the older version, it usually takes seconds to load the GUI.
1.7.1, or something older? I rearranged some of the code a few months ago but the underlying functions haven't changed much since April - however, the underlying modules do change too and it is quite possible that a bug was introduced at some point. thanks, Nat
