VMTKMESHDATAREADER(1)

💖 VMTKMESHDATAREADER 💖

okay bestie, this is section 1 of the manuals (User Commands, no cap), and the command itself is literally called vmtkmeshdatareader. Yes that's a mouthful. Yes it's iconic. Let's get into it 🫶

---

✨ NAME ✨

vmtkmeshdatareader — it's a vmtk script, and the script is named vmtkmeshdatareader. That's the whole name section. She said "my name is my name" 💅

---

🌸 DESCRIPTION 🌸

So the vibe here is: automatic piping. There's automatic piping happening (vmtkmeshdatareader), and also option parsing (vmtkmeshdatareader). It's giving plumbing but make it ✨scientific✨.

What does it actually do tho? Here's the tea:

vmtkmeshdatareader : read data associated with a mesh

That's the mission statement. Read data. Attached to a mesh. Slay 🔥

🎀 Input arguments 🎀

the stuff you feed in, the ingredients, the little guys:

• -id Id (str,1); default=0 — the script id. It's the id. Of the script. Default 0, as one does.
• -handle Self (self,1) — handle to self 🫶 yes, self-love is a valid input argument, we love to see it.
• -disabled Disabled (bool,1); default=0 — disable execution and piping. So if you set this, it just... doesn't. Very "not me showing up today" energy.
• -i Mesh (vtkUnstructuredGrid,1) — the input mesh. THE mesh. the main character mesh 👑
• -ifile MeshInputFileName (str,1) — filename for the default Mesh reader.
• -directory DataFileDirectory (str,1); default=. — directory where the data files reside. Default is just . (yep, right here, in your current folder, bestie).
• -prefix DataFilePrefix (str,1) — data file name prefix — like foo_ for example.
• -datafile DataFileName (str,1) — data file name (like foo.dat for example), excluding directory. Careful: this one overrides prefix. She's powerful. She said "I go first" 💅
• -filetype DataFileType (str,1); default=tetr.vel — data file name type. Your choices are: tetr.out, tetr.vel, tetr.wss, tetr.pres, tetr.ini, pointdata. Pick your fighter 🌈
• -arrayprefix ArrayNamePrefix (str,1) — prefix to prepend to array names in output. A little name tag. So cute 🎀
• -tetrinfile TetrInFileName (str,1) — name of the tetr.in file.
• -compressed Compressed (bool,1); default=1 — toggle reading gzip compressed file. Default is on, so compressed is the moment unless you say otherwise.
• -unnormalize UnNormalize (bool,1); default=1 — unnormalize quantities. Note: tetr.* only. Don't try it on anything else, that's not her jurisdiction.
• -minvarid MinVariableId (int,1) >= 0; default=-1 — read variables starting from the nth column. pointdata only, iykyk.
• -maxvarid MaxVariableId (int,1) >= 0; default=-1 — read variables up to the nth column. Also pointdata only, obviously, keeping it symmetrical, we love a matching set 🦋
• -ofile MeshOutputFileName (str,1) — filename for the default Mesh writer.

💜 Output arguments 💜

what she gives you back, the results, the payoff:

• -id Id (str,1); default=0 — script id. (Yes it's here too. She contains multitudes. Both an input and an output. Literally all of us fr fr.)
• -handle Self (self,1) — handle to self. (Also both. Self is eternal like that.)
• -o Mesh (vtkUnstructuredGrid,1) — the output mesh!! The glow-up mesh. The before and after 🌟

---

okay a lil heads up bestie: -datafile fully overrides -prefix, and the -minvarid / -maxvarid / -unnormalize options only work for their specific file types (pointdata and tetr.* respectively). Read the one-liners. They're telling you something 💀
