load_xrmsd {MDplot}

Loading function for xrmsd()

Description

Loads matrix information from the specified file.

Usage

load_xrmsd(  path,
             factor = 1,
             removeLowerHalf = TRUE,
             mdEngine = "GROMOS"  )

Arguments

path

Specifies the input file.

factor

In case the RMSD values are given in

nm * factor

, the factor can be specified. If the unit is already nanometers, 1 is the appropriate value.

removeLowerHalf

If TRUE, the lower half of the plot will be white.

mdEngine

Argument distinguishes between input formats based on the molecular dynamics engine used. Currently available: "GROMOS", "GROMACS" and "AMBER".

Value

Returns a nx3-matrix, with the first two columns holding the position (x- and y-axis) and the third the respective RMSD value.
