[Chimera-users] delegate

[Zoe Cournia]

Dear Conrad,

Thanks for the prompt reply. I have a program available (called "chop")
that is designed to be run from within UCSF midas. I have extensively used
midas with chop in the past successfully and now that I have changed labs
I would like to continue using chop with the Midas (or Chimera) graphical
interface.

The program's manual states that:
"Although the midas program does lack a real scriptable language, it does
provide a mechanism to interact with external program called the delegate
utility. This mechanism is completely described in their manual but
briefly, the delegate utility sets a name or prefix that when used at the
beginning of a line will cause the remainder of the line to be sent to the
delegate program. After the line is sent midas reads as its standard
output a midas command that is generated by the delegate program, in this
case "chop"."

Therefore, the first command I was using was:
delegate start chop chop –i 1aaq.pdb
which starts the chop program and defines “chop” as the prefix
for commands to be sent to delegate. Then a series of "chop" commands were
input into midas.

Unfortunately, it is not possible for me to re-write the chop program. If
delegate was not carried over to Chimera and there is no other way to
start chop from within Chimera, is there a way to access the Midas
installer/source code in order to install and use it?
Chop does not start Chimera by itself.

Thanks a lot for your help. I am looking forward to hearing from you!

Best wishes
Zoe
