VMTKPOINTSPLITEXTRACTOR(1)

💖 VMTKPOINTSPLITEXTRACTOR 💖

okay bestie, welcome to vmtkpointsplitextractor, section 1 of the User Commands manual, no cap. this is a vmtk script and she is that girl. let's get into it ✨

🎀 NAME 🎀

vmtkpointsplitextractor — literally the vmtk script called vmtkpointsplitextractor. that's the name, that's the vibe. 🦋

🌸 DESCRIPTION 🌸

so here's the tea: vmtkpointsplitextractor does automatic piping, and it parses options like it was born for it. the script name gets passed around like the group chat link. iykyk.

vmtkpointsplitextractor : split a centerline at specific xyz coordinates 💅

below is everything it takes in, and everything it hands back. don't skip a single one, they're all important, fr fr.

🫶 Input arguments

• -id Id (str,1); default=0 — this is the script id, bestie. every script's lil name tag.
• -handle Self (self,1) — handle to self. she's holding her own hand, iconic.
• -disabled Disabled (bool,1); default=0 — flip this and the script won't execute and won't pipe. she's off duty, do not disturb 🙈
• -i Centerlines (vtkPolyData,1) — the centerlines you're feeding in. the main character data. 👑
• -ifile CenterlinesInputFileName (str,1) — filename for the default Centerlines reader. (that's the reader doing the reading, not you.)
• -groupidsarray GroupIdsArrayName (str,1); default=GroupIds — name of the group ids array.
• -tractidsarray TractIdsArrayName (str,1); default=TractIds — name of the tract ids array.
• -centerlineidsarray CenterlineIdsArrayName (str,1); default=CenterlineIds — name of the centerline ids array.
• -radiusarray RadiusArrayName (str,1); default=MaximumInscribedSphereRadius — name of the radius array. yes that whole long name, she said what she said.
• -blankingarray BlankingArrayName (str,1); default=Blanking — name of the blanking array.
• -splitpoint SplitPoint (float,3); default=[0.0, 0.0, 0.0] — the xyz spot where the split goes down. three whole floats. 💅
• -gaplength GapLength (float,1) >= 0.0; default=1.0 — the gap length. note the constraint: she must be >= 0.0, okay? negative is not the vibe.
• -tolerance Tolerance (float,1) >= 0.0; default=0.0001 — the tolerance. also has to be >= 0.0. respect the boundary, periodt.
• -ofile CenterlinesOutputFileName (str,1) — filename for the default Centerlines writer. (writer = outgoing, reader = incoming, keep it straight 🧚)

⭐ Output arguments

• -id Id (str,1); default=0 — script id again. she contains multitudes.
• -handle Self (self,1) — handle to self, back for round two. 💜
• -o Centerlines (vtkPolyData,1) — the centerlines coming back out at you. the glow-up. ✨
• -groupidsarray GroupIdsArrayName (str,1); default=GroupIds — name of the group ids array, on the way out.
• -tractidsarray TractIdsArrayName (str,1); default=TractIds — name of the tract ids array, output version.
• -centerlineidsarray CenterlineIdsArrayName (str,1); default=CenterlineIds — name of the centerline ids array, output version.
• -blankingarray BlankingArrayName (str,1); default=Blanking — name of the blanking array, output version.

heads up bestie: the output side does not list -radiusarray, -splitpoint, -gaplength, or -tolerance. that's not me being lazy, that's literally what's written. don't come for me 💀

that's the whole page, you ate it. 🍓

with love, your favorite unix bestie — this was vmtkpointsplitextractor version 1.5, dated April 2026. bye babe, go split some centerlines 🦋💖
