MS_findMappedNodes {MetaboSignal} | R Documentation

## Map gene IDs or metabolite IDs onto the network

### Description

This function can be used to find out if a set of genes or metabolites of interest can be mapped onto the network.

### Usage

    MS_findMappedNodes(nodes, network_table)

### Arguments

`nodes` | character vector containing the IDs of the genes or the metabolites to be mapped onto the network. Remember that Entrez IDs or gene symbols can be transformed into KEGG IDs using the function "MS_convertGene( )".
`network_table` | three-column matrix where each row represents and edge between two nodes. See function "MS_keggNetwork( )".

### Value

A list reporting which genes or metabolites can or cannot be mapped onto the network.
