Hello Aji,
Perhaps, the following can help as I'm also new to using Vampire. My operating system is Ubuntu 20.04.2.0 LTS [1].
As as described at [2], I installed Vampire under Ubuntu using:
As described on slide 60 of [3], I followed the instructions
there to build the vdc executable:
I copied and pasted from the bilayer tutorial [4] to create a input and bilayer.mat file.
I followed Richard's instructions at [5] for running the calculation:
username@computername:~/bilayer$ ls
bilayer.mat input
username@computername:~/bilayer$
/home/username/vampire/vampire-serial

username@computername:~/bilayer$ rasmol -xyz crystal.xyz
In rasmol, I clicked Display -> Molecular Surface, then the
mouse was used to rotate the view. I got an image similar to, but
perhaps unfortunately different from that seen on the bilayer
tutorial page [4].
