Hello,

I am modifying some Ringer files for my own needs, but I am running into a weird issue. If I run Ringer via typical means:

it works fine. However, when I step through it in what I think is my version of IDLE ("$CHIMERA_HOME/bin/chimera --nogui --nostatus --script `which idle2.7`

/usr/bin/idle2.7", with `which idle2.7` returning "/usr/bin/idle2.7"), I run into this error:

Any suggestions?
