generateLpFileCarnival

Description

generateLpFileCarnival

Usage

generateLpFileCarnival(
  perturbations = NULL,
  measurements,
  priorKnowledgeNetwork,
  weights = NULL,
  carnivalOptions = defaultLpSolveCarnivalOptions()
)

Arguments

perturbations

(optional, if inverse CARNIVAL flavour is used further) vector of targets of perturbations.

measurements

vector of the measurements (i.e. DoRothEA/VIPER normalised enrichment scores)

priorKnowledgeNetwork

data frame of the prior knowledge network

weights

(optional) vector of the additional weights: e.g. PROGENy pathway scores or measured protein activities.

carnivalOptions

the list of options for the run. See defaultLpSolveCarnivalOptions(), defaultCplexCarnivalOptions, defaultCbcCarnivalOptions.

Details

Prepares the input data for the run: tranforms data into lp file and .Rdata file. These files can be reused to run CARNIVAL without preprocessing step using runCarnivalFromLp(..)

Value

paths to .lp file and .RData file that can be used for runFromLpCarnival()

Examples

load(file = system.file("toy_perturbations_ex1.RData",
                        package="CARNIVAL"))
load(file = system.file("toy_measurements_ex1.RData",
                        package="CARNIVAL"))
load(file = system.file("toy_network_ex1.RData",
                        package="CARNIVAL"))
