Hello! I'm new on molecular dynamics, by far I have been collecting knowledge regarding molecular dynamics and all the complex theories that must be taken into account when performing that kind of tasks.

Currently I'm following a tutorial on GROMACS and I need to perform a dynamic simulation of a dendrimer for a course so I want to know from where can I get a dendrimer input file for GROMACS? and where and how can I get or build the structure of this nanoparticle? just need a first guidance.

thanks for your time.
