How to run sbproj using sbiosimulate with a selected dose in SimBiology?

Consider the predefiend doses '250 mg bid', '250 mg tid', etc. in the model AntibacterialPKPD.sbproj, see screenshot

I am unable to load selected doses, e.g. only '250 mg bid', so far I tried this

clear variables

modelName = 'AntibacterialPKPD.sbproj';
sbioloadproject(modelName,'m1')
[time,x,names] = sbiosimulate(m1,[],[],'250 mg bid')

but get error

>> testAnt
Error using sbiosimulate (line 136)
Expected input number 4, DOBJ, to be one of these types:

SimBiology.Dose
Error in testAnt (line 5)
[time,x,names] = sbiosimulate(m1,[],[],'250 mg bid')

Any comments would be very appreciated!

OK, I found it out, I was missing the dose object

modelName = 'AntibacterialPKPD.sbproj';
sbioloadproject(modelName,'m1')
d1 = getdose(m1, '250 mg bid')

[time,x,names] = sbiosimulate(m1,[],[],d1)
plot(time,x(:,1));
