VMTKCENTERLINEMERGE(1)

💖 NAME 💖

vmtkcenterlinemerge — bestie it's a vmtk script, and its whole job is merging centerline tracts that belong to the same groups 🫶

✨ DESCRIPTION ✨

Ok so picture this: automatic piping, and then vmtkcenterlinemerge shows up and starts parsing options like it's the main character. That's literally the vibe here.

vmtkcenterlinemerge : merge centerline tracts belonging to the same groups 🧚 no cap, that's the entire assignment.

🌸 Input arguments (the stuff you feed it) 🌸

• -id Id (str,1); default=0 — the script id, it's giving ✨identity✨
• -handle Self (self,1) — handle to self, it's holding its own hand fr
• -disabled Disabled (bool,1); default=0 — disable execution and piping, i.e. the "not me participating today 💀" switch
• -i Centerlines (vtkPolyData,1) — the input centerlines, the whole point tbh
• -ifile CenterlinesInputFileName (str,1) — filename for the default Centerlines reader 📖
• -radiusarray RadiusArrayName (str,1); default=MaximumInscribedSphereRadius — name of the array where centerline radius is stored 🎀 yes that default is a whole mouthful, iconic of it
• -groupidsarray GroupIdsArrayName (str,1); default=GroupIds — name of the array where centerline group ids are stored
• -centerlineidsarray CenterlineIdsArrayName (str,1); default=CenterlineIds — name of the array where centerline ids are stored
• -tractidsarray TractIdsArrayName (str,1); default=TractIds — name of the array where centerline tract ids are stored 🦋 (yes this is the whole reason the script exists, bestie)
• -blankingarray BlankingArrayName (str,1); default=Blanking — name of the array where centerline blanking information about branches is stored 🙈
• -length Length (float,1) >= 0.0; default=0.0 — length of the resampling interval 📏
• -mergeblanked MergeBlanked (bool,1); default=1 — toggle generation of segments for blanked groups 🔥
• -ofile CenterlinesOutputFileName (str,1) — filename for the default Centerlines writer ✍️

💅 Output arguments (the stuff it hands back) 💅

• -id Id (str,1); default=0 — script id, yes again, it gets a lil encore 👑
• -handle Self (self,1) — handle to self, also back for round two
• -o Centerlines (vtkPolyData,1) — the output centerlines, your reward for all that flag-typing ⭐

Heads up bestie: -id and -handle really do show up in both the input and the output arguments. Not a typo, not me being extra — that's just how it's listed. 🫶

so yeah that's the whole page, you ate that 💜 This one's from vmtkcenterlinemerge 1.5, dated April 2026, and it lives in the User Commands section of the manual. Go forth and merge those tracts, mwah 💋🌈
