sybilSBML (version 3.1.2)

writeSBML: Exports a Metabolic Network in SBML Format

Description

The function exports a metabolic network from S4 object of the class modelorg in SBML format. The function returns TRUE if the SBML file is successfully built.

Usage

writeSBML(morg=NULL,level=2,version=4,fbcLevel=0,
             filename="export.xml",
             recoverExtMet=FALSE,
             printNotes=TRUE,
             printAnnos=TRUE,
             validation=FALSE)

Arguments

morg

An S4 object of the class modelorg.

level

A single integer value containing the SBML level for the exporting SBML file. Default: 2.

version

A single integer value containing the SBML version for the exporting SBML file. Default: 4.

fbcLevel

A single integer value containing the fbc package version for the exporting SBML file. Default: 2.

filename

SBML filename for exporting the model. Default: "export.xml".

recoverExtMet

Boolean: recover external metabolites and refer them to compartment "BOUNDARY". Default: FALSE.

printNotes

Boolean: print Notes from original SBML file . Default: TRUE.

printAnnos

Boolean: print Annotations from original SBML file . Default: TRUE.

validation

Boolean: print containing errors for xml file . Default: TRUE.

Value

A single boolean value for a successful export.

Details

The library libSBML is used to export a modelorg to a SBML file.

If sybilSBML was built with a libSBML version, that was not including the FBC plugin and the Groups plugin, the function is not writing an output file and returns FALSE. Please make sure that you build sybilSBML with the libSBML version containing the FBC and Group plugins (check out installation details).
