Multipath

Creating integrated reproducible pathway multilayer models

Introduction

Biological pathway data integration has become a topic of interest in the past years. This interest originates essentially from the continuously increasing size of existing prior knowledge as well as from the many challenges scientists face when studying biological pathways. Multipath is a framework that aims at helping re-trace the use of specific pathway knowledge in specific publications, and easing the data integration of multiple pathway types and further influencing knowledge sources. Using Multipath, BioPax-encoded pathways can be parsed and embedded into multilayered graphs. Modifications can be applied to these graphs to generate different views. The package is implemented as a part of the Multipath Project directed by Dr. Frank Kramer .

Installation

Preinstallation

Multipath depends on multiple packages. The packages are the following: UniProt.ws, dbparser, rBiopaxParser, mully, TCGAretriever, stringr, svMisc, uuid, dplyr, crayon Please make sure to install the packages UniProt.ws, rBiopaxParser and mully before using the package.

To install the UniProt.ws package:

if (!requireNamespace("BiocManager", quietly = TRUE))
    install.packages("BiocManager")

BiocManager::install("UniProt.ws")

To install the mully package:

require(devtools)
install_github("frankkramer-lab/mully")
library(mully)

To install the rBiopaxParser package:

require(devtools)
install_github("frankkramer-lab/rBiopaxParser")
library(rBiopaxParser)

Installation via Github

require(devtools)
install_github("frankkramer-lab/Multipath")
library(Multipath)

Test the package

In this section, we provide a demo to test the package by calling some of the function. To run the script, you need to download the Signaling by Wnt from the Reactiome database in the BioPax format.

Create a mully graph from a BioPax-encoded pathway

wntBiopax=readBiopax("wntpathway_reactome.owl")
pathwayID=listPathways(wntBiopax)$id[1]
wntmully=pathway2Mully(wntBiopax,pathwayID)
plot3d(wntmully,layers=T,vertex.label=NA,edge.width=5,edge.arrow.size=5)

Generate Views

view1=pathwayView(wntmully,"View1")
view1=addStep(view1,action = "remove",element="layer",name="Rna",trans = T)
suppressWarnings(plot3d(view1$modified))

view2=pathwayView(wntmully,"View2")
view2=addStep(view2,action = "remove",element="layer",name="PhysicalEntity",trans=T)
suppressWarnings(plot3d(view2$modified))

view3=pathwayView(wntmully,"View3")
view3=addStep(view3,action = "remove",element="layer",name="Complex",trans=T)
suppressWarnings(plot3d(view3$modified))
