GMX-DUMP(1)

💅 NAME 💅

gmx-dump — bestie, it makes your binary files human readable ✨

---

🦋 SYNOPSIS 🦋

gmx dump [-s <.tpr>] [-f <.xtc/.trr/...>] [-e <.edr>] [-cp <.cpt>]
         [-p <.top>] [-mtx <.mtx>] [-om <.mdp>] [-[no]nr]
         [-[no]param] [-[no]sys] [-[no]orgir]

---

🌸 DESCRIPTION 🌸

okay so listen. gmx dump is the girl who reads the vibes of your files and then tells you, in plain language, what's actually inside them. 🫶

It takes a run input file (.tpr), a trajectory (.trr/.xtc/tng), an energy file (.edr), a checkpoint file (.cpt), or a topology file (.top), and prints the whole thing out to standard output in a readable format. literally just vibes-to-text conversion.

And ngl, this one is essential — like, life-saving essential — when your run input file is acting up and you need to check what's actually in it. bestie this is your first stop when something smells wrong. 😭

✨ OPTIONS ✨

📥 Options to specify input files

• -s <.tpr> (Optional) — the run input file you wanna dump 👑
• -f <.xtc/.trr/...> (Optional) — trajectory file to dump, and she comes in many flavors: xtc trr cpt gro g96 pdb tng h5md 🌈
• -e <.edr> (Optional) — energy file to dump ⚡
• -cp <.cpt> (Optional) — checkpoint file to dump 🎀
• -p <.top> (Optional) — topology file to dump 🧚
• -mtx <.mtx> (Optional) — Hessian matrix to dump 🔥

📤 Options to specify output files

• -om <.mdp> (Optional) — spits out a grompp input file from the run input file 💖

🎛️ Other options

• -[no]nr (default: yes) — show index numbers in the output. turning them off makes comparing dumps easier, but heads up: it also creates a useless topology. 💀 pick your fighter.
• -[no]param (default: no) — show parameters for each bonded interaction. and if you're comparing dumps? lowkey combine this with -nonr, it's the move. 👑
• -[no]sys (default: no) — list the atoms and bonded interactions for the whole system, instead of for each molecule type one by one. 🌸
• -[no]orgir (default: no) — show the input parameters from the tpr exactly as they were written by the version that produced the file, instead of how the current version reads them. time capsule behavior, honestly. 🕰️

🙈 KNOWN ISSUES 🙈

• The .mdp file produced by -om can not be read by grompp. it's giving forbidden file, bestie. don't do it. 😭
