Hi David,

Did you try vmd -e?

Subject: vmd-l: Issue running vmd and tk commands on my computer through script

Dear everyone,

I have quite a bit of data and I am hoping to speed up the analysis of many individual vmd runs by automating it; however, I have been having a problem with this (and just to note that this is running on an Ubuntu 20.04LTS I have and not a server. I created a script which attempts to open vmd using specific files, and then run 1 script with a condition followed by a second script. Then exits vmd and changes the names of the 2 output files. Then it is meant to restart VMD and do this all over again. I have tried using (pipes | ) and echos, and tried -args with the commands after it and all other routes I could conceive of to achieve this but in the end what occurs is that either VMD has errors or most commonly it opens vmd, and then it appears that it doesn't read the next line and when I manually exit out then it attempts to execute the following lines. I am not sure how to get VMD to understand these commands as being for it's command line as all of these lines work properly when I put them in manually but I cannot get them to work automatically without constant involvement on my part. I am sorry if this is a basic issue but I am self taught in Molecular Dynamics and as such I find that I often find myself jumping in the deep end.

The script lines
vmd start_time-Protein.pdb md-Protein-fit-0000-0025.xtc -dispdev none # Open VMD with structure and trajectory
source /media/david/ORIGIN/PhD-Ubuntu/Gromacs\ Work/Work\ Files\ and\ Programs/sasa.tcl # track residue SASA
residue 35 # must fill in residue number
source ./H2O-Protein-Script.tcl
mv ./SASA_residue\ 35.dat ./Data-SASA-E-Protein_0000-0025.dat # rename SASA Glutamate Data File
mv ./Data-H2O.xvg ./Data-H2O- Protein-0000-0025.xvg # rename H2O file

# After this point. the pattern is meant to repeat opening different VMD sessions with the same sourcing and similar file name changes etc. For thousands of analyses.

I know I am probably missing out on something minor but I don't understand why my commands are not being entered through the VMD command line.
