Hi Norman,
Looks great! thanks! just one more question: sourcing the tcl through the tcl-force script
is different from to write it down directly in the tcl-force script? Because when
I write it down directly I receive the error from which I defer that the script can not realize the commands
regarding the side chain..
All the Best,
Zeynab

Guess no! A good way
to do it, is do write a TCL script for VMD to prepare some kind of config file
containing the information you need and source this configuration within your
TCLForces script. Like (expects to have a molecule loaded already):
prepare.tcl:
puts “Input) Molid?”
gets stdin molid
puts “Input) Resids?”
gets stdin resids
array unset sidechains; #save restart
array set sidechains {}
foreach resid $resids {
set sel [atomselect $molid “resid $resid and sidechain”]
set sidechains($resid) [$sel get index]
$sel delete
}
set fp [open “prepared.conf.tcl” w]
puts $fp [list array set sidechains [array get sidechains]]
close $fp
puts “Info) Done, you’re are now prepared!”
So within your TclForces script:
source prepared.conf.tcl
#loop over sidechains
foreach resid [array names sidechains] {
puts “Now doing something with sidechain of resid $resid having this
atoms: $sidechains($resid)”
}

Betreff: namd-l: How to refer to side-chain via tcl-force scripting?
Dear all,
I need to impose force on the side-chain of some residues, using
tcl-force scripting. Do you know if
the tcl-force interface provides any command so that you can refer
to side-chain of the desired residue?
Thanks in advance for your help,
Zeynab
