\title{
Convert HEINZ output to graph
}
\description{
Function to convert the HEINZ output to a graph object, or if the output is in matrix form, it will create a list of graphs.
The function needs the node and the original network, from which the module is calculated.
}
\usage{
readHeinzGraph(node.file, network, format=c("graphNEL", "igraph"))
}
\arguments{
  \item{node.file}{
Heinz node output file.
}
  \item{network}{
