TEND-ANVOL(1)

💖 TEND-ANVOL(1) 💖

okay bestie, welcome to tend-anvol — she lives in the tend family of User Commands and her whole entire job is applying an anisotropy metric to a DT volume 🧠✨

✨ NAME ✨

tend-anvol — apply an anisotropy metric to a DT volume 🎀

---

🌸 SYNOPSIS 🌸

tend anvol -a <aniso> [-t <thresh>] [-i <nin>] [-o <nout>]

---

🦋 DESCRIPTION 🦋

So basically: she applies an anisotropy metric to a DT volume. that's the vibe. 💅

and here's the lil plot twist you need to know — the anisotropy value is gonna be zero in all the locations that don't meet the given confidence threshold. like, if you don't clear the bar, you get a zero, no cap. 🫶

---

💅 OPTIONS 💅

• -a <aniso> — which anisotropy metric are we plotting, bestie? 🌈 note that all the Westin metrics come in two versions. currently supported:
  • "cl1", "cl2" — Westin's linear ✨
  • "cp1", "cp2" — Westin's planar 🌸
  • "ca1", "ca2" — Westin's linear + planar 🦋
  • "cs1", "cs2" — Westin's spherical 🎀
  • "ct1", "ct2" — GK's anisotropy type (cp/ca) 👑
  • "ra" — Basser/Pierpaoli relative anisotropy/sqrt(2) 💜
  • "fa" — Basser/Pierpaoli fractional anisotropy 🔥
  • "vf" — volume fraction = 1-(Basser/Pierpaoli volume ratio) 🍓
  • "tr" — trace 🌈
• -t <thresh> — confidence threshold, and she's a float babe. default: "0.5" ⭐
• -i <nin> — input diffusion tensor volume, the main character of the operation. default: "-" 🌟
• -o <nout> — output image (floating point) (string). default: "-" 💖

💀 reminder for the girlies: that -a flag is not optional, it's giving required. and remember the threshold thing — below -t and you're getting zeros, not drama.

mwah 💋 that's the page! this one's from April 2021, living in the TEND-ANVOL(1) section of the User Commands manual — go forth and plot some anisotropy, bestie 🧚💜
