readQSM.treegraph: readQSM.treegraph

In ashenkin/treestruct: Provides Classes for Analysis and Manipulation of Tree Structure Models

Description

reads in a QSM file in treegraph format and passes back cylinder and branch data

Usage

readQSM.treegraph(qsmfile, qsmver = "by_name")

Arguments

qsmfile	path to treegraph file
qsmver	version of treegraph used to make the treegraph file, Default: by_name

Details

Treegraphs are described by nodes that connect cylinders, as opposed to internodes as in treeQSM. In addition, treegraphs sometimes have furcations at the most basal node (think of a tree that branches at the soil surface). In these cases, treestruct's use of internodes instead of nodes as the most basic element breaks down, as there is no way to indicate that the two (or more) most basal cylinders should be connected. To get around this issue, we add a 0-length, 0-width cylinder at the base of treegraph objects with basal furcations to enable that connectivity. We must make sure that analyses that could be thrown off by this extra cylinder make accomodations for it.

Value

a 3-element list of file (filename), CylData, and BranchData
