Hi Christos,
It is a syntax erro mol, it defined as variable , in set $mol, change it by set mol only.
Best,

Asunto: vmd-l: Using BigDCD on Simulation Files Located on Mapped Network Drive
Hello,
I have run some large simulations with NAMD and the files are located on a mapped network drive on my Windows 10 computer. My simulation file is around 45 GB, so I would like to be able to use bigdcd to analyze the simulation. I have downloaded the script, and I am trying to calculate the center of mass from the example script.
Here is my script:
---------------------------------------------------------------------------------------------------
source C:/Users/Christos/Documents/VMD_Scripts/bigdcd.tcl
proc mycenter { frame } {
global all
puts "$frame: [measure center $all weight mass]"
}
set $mol [mol new psf J:/pc/Wildtype_100ns_Test1/run/Wildtype_100ns_Test1_QwikMD.psf waitfor all]
set all [atomselect $mol all]
$all global
bigdcd mycenter J:/pc/Wildtype_100ns_Test1/run/MD.dcd
------------------------------------------------------------------------------------------------------
However, when I run this script, I get the following error:
can't read "mol": no such variable
How can I fix this error? I am providing the full path to the psf and dcd files that are located on my mapped network drive.
Best,
Christos
