In sybil: Efficient Constrained Based Modelling

Description Usage Arguments Details Value Author(s) References

The function modelorg2ExPA writes the content of an instance of class modelorg to text files in a format which can be read by the program ExPA to compute extreme pathways.

  modelorg2ExPA(model, fname = NULL, exIntReact = NULL,
                filepath = ".", suffix = "expa",
                tol = SYBIL_SETTINGS("TOLERANCE"))

`model`	An object of class `modelorg`.
`fname`	An single character string giving the filename to write to. Default: `<model_id>.expa`.
`exIntReact`	An object of class `reactId`, character or integer, giving id's of internal reactions to exclude in the ExPA file. Default: `NULL`.
`filepath`	A single character string giving the path to a certain directory in which the output files will be stored. Default: `"."`.
`suffix`	A single character string giving the file name extension. Default: `"expa"`.
`tol`	A single numeric value giving the limit of tolerance. An element S[i,j] of the stoichiometric matrix is treated as non-zero, if S[i,j] > tol is true. Default: `"expa"`.

The function modelorg2ExPA produces input files for the program ExPA. With ExPA, it is possible to calculate extreme pathways in metabolic networks.

The function produces a warning, if a reaction contains non-integer stoichiometric values, because they are not compatible with the ExPA program.

Returns TRUE invisibly on success.
