aRchi (version 2.1.3)

Truncate_QSM: Truncate a QSM

Description

Truncate a QSM at a radius threshold

Usage

Truncate_QSM(
  aRchi,
  threshold = NULL,
  Keepdaughters = FALSE,
  plotresult = FALSE
)
# S4 method for aRchi
Truncate_QSM(
  aRchi,
  threshold = NULL,
  Keepdaughters = FALSE,
  plotresult = FALSE
)

Value

An aRchi file with the QSM truncated

Arguments

aRchi

an object of class aRchi with at least a QSM and a Paths table.

threshold

numeric. The radius threshold in meter.

Keepdaughters

logical (default = FALSE). Keep the daughters of the last segment retained even if they are lower than the threshold.

plotresult

logical (default = FALSE). Show the results in a 3d plot if TRUE

Details

The threshold is applied to a whole segments. In other word, if a segment has at least one cylinder lower than the threshold it is removed as well as everything upstream (except the direct daughters if Keepdaughters=TRUE).

# Truncate the QSM: 5cm radius threshold
Truncated_Tree1_aRchi=Truncate_QSM(Tree1_aRchi,plotresult = TRUE,threshold = 0.05)
