Topology versus initial configuration

GROMACS version: 2023.2/2024.1
GROMACS modification: Yes

Hi all! I’m so sorry for the naive question, but I wanted to check whether topology files are initial-position specific, or if they just provide the essential information for binding, etc. I’m hoping to run simulations with different initial phi/psi space conformations, and I wanted to confirm that I can still just use the general topology file, or if needs to be adjusted. Thank you so much in advance!

The topology file can remain the same regardless of input coordinates.

That is phenomenal news! Thank you @MagnusL
