writeSBML: Exports a Metabolic Network in SBML Format
In sybilSBML: 'SBML' Integration in Package 'Sybil'

Description Usage Arguments Details Value Note Author(s) References See Also Examples

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.

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

`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`.

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).

A single boolean value for a successful export.

The function writeSBML makes use of the library libSBML (http://www.sbml.org).
