Dear all, I have some trouble with SBML export using the package 'rsbml'. The following example of saving a very simple model to file gives an error on my machine: require('rsbml') com<-new("Compartment",id="default_compartment",name="default_compartm ent",size=1) sp<-new("Species",id="s1",name="s1",compartment=com at id,initialConcentration=10) re<-new("Reaction",id="r1",name="r1",kineticLaw=new("KineticLaw",math= as.expression(0)),reactants=list(new("SpeciesReference",species="s1",s toichiometry=1))) sbml_model<-new("Model",id="mymodel",name="mymodel",compartments=list( com),species=list(sp),reactions=list(re)) sbml_doc<-new("SBML",level=as.integer(2),ver=as.integer(2),model=sbml_ model) rsbml_write(sbml_doc, file="myfile.xml") The error occurs in creating the SBML object, the message is: Error in validObject(.Object) : invalid class "SBML" object: FALSE If the KineticLaw in the reaction is NULL, e.g.: re<-new("Reaction",id="r1",name="r1",reactants=list(new("SpeciesRefere nce",species="s1",stoichiometry=1))) the SBML export works without throwing errors. Also, if I create a document with SBML Level 2, version 1 instead of Level 2, version 2 in the example above, the code runs without errors. However, then only the SBML header is written to file and nothing else. I went through the documentation and tried it with the example models as well, but I cannot find a solution. I hope I understood right how to create a document object from a model object. I installed rsbml via the bioconductor and have libSBML version 4.0.1 (that's whats written in the generated SBML) on Linux with R 2.13.1. Does anybody know what could be the problem here? Many thanks in advance, Hannes Hettling

Well, it took a bit longer than I expected, but I have things now working under libsbml 5.x. Should still work under 4.x (please let me know). I have also fixed the validity checking that was causing your problem. You'll need the devel (2.13.1) or wait for the release next month.

Dear Michael, Thanks a lot for your help! I got it to work with the development version of the package and libsbml 5. The package does not compile anymore with libsbml 4; I guess the package uses the development version of SOSlib, which says it only works with libsbml 3.0.2 or the latest devel version, so it might be good to change the package requirements. I also had to downgrade sundials from 2.4.0 to 2.3.0 because of SOSlib. Another thing is that the package gave an error creating an SBML document because it could not find the function "rsbml_perform_check", so I changed line 5 in SBML.R and set the variable "valid" to TRUE, which is a bit of a hack, but it works for now. Is this a check for the validity of the SBML document and is this check done with SOSlib?

I found another small problem with writing my model to file: Whenever there are any parentheses in the math expression in a KineticLaw, the <kineticlaw/> tag in the written SBML file is empty. Even for a very simple reaction like: re<-new("Reaction",id="r1",name="r1",kineticLaw=new("KineticLaw",math= as.expression(parse(text="(A)"))),reactants=list(new("SpeciesReference ",species="s1",stoichiometry=1))) I checked my document object within the "rsbml_write" and "rsbml_xml" functions and the math expression is correct there. I wrote a small C program to try if the writeSBML function in libsbml can even handle parentheses, and it does. In the io.c file, the generic libSBML functions are called.. Therefore I suspect that something goes wrong in in creating the SBMLDocument c-object (in the doc.c file?)... do you think this is a god place to look? I do not want to bug you with requests all the time, and I will look further into it, it would be great if you could tell me if I am searching in the right place. After all I do not have experience with the R-to-C interface and find it quite hard to dubug.
