The cepsIonic executable is compiled together with ceps. It computes the solution of an ionic model, without any spatial dimension. You can run it from command line:

$> ./cepsIonic myInputFile [-v] [-p]

It will generate a file model.dat where model is replaced by the name of the ionic model.

of the input file

There are much less possible items in the input file than the ceps executable. See this section for details on syntax.

Keyword	Value format	Default value	Description
output directory	path	.
output period	scalar real value	time step	Time period at which a line will be written in the output file
start time	scalar real value	0.	starting time of the ODE system, in milliseconds
end time	scalar real value	100.	end time of the ODE system, in milliseconds
time step	scalar real value	0.01	time step in milliseconds.
ionic model	one of TTP06_Endo, TTP06_MidMyo, TTP06_Epi, MS03, CRN98, BR77, ORDMD16_Endo, ORDMD16_Midmyo, ORDMD16_Epi	—	Mandatory parameter. See Ionic Models for more information.
ionic model solver	STRING	FBE	Check the ODE Solvers section for a list available ODE solvers
stimulation	Comma-separated list of STRINGS	–	Each string can contain the elements defining a new function.

See this Ionic Models page for inputs of each ionic model.
