Error message for conditional statement in $ODE

[Wendy723]

I was trying to write a conditional statement in $ODE. It gave me a error message as below. Could anyone let me know how should I write this statement? I tried to put double mt1 = self.mtime(Tmax); in $MAIN as introduced in the user guide. It gave a similar error message.

$ODE if(TIME<=Tmax) dxdt_EFFE = p*EFFE; if(TIME>Tmax) dxdt_EFFE = - alpha*EFFE;

Example-mread-source.cpp: In function ‘void _model_Example_ode__(const double*, const double*, double*, const dvec&, const double*)’: /opt/scp/software/mro/3.5.1-foss-2017a/lib64/R/site-library/mrgsolve/base/modelheader.h:100:14: error: ‘self’ was not declared in this scope #define TIME self.time ^ Example-mread-source.cpp:104:4: note: in expansion of macro ‘TIME’ if(TIME<=Tmax) dxdt_EFFE = p*EFFE; ^~~~ /opt/scp/software/mro/3.5.1-foss-2017a/lib64/R/site-library/mrgsolve/base/modelheader.h:100:14: error: ‘self’ was not declared in this scope #define TIME self.time ^ Example-mread-source.cpp:105:4: note: in expansion of macro ‘TIME’ if(TIME>Tmax) dxdt_EFFE = - alpha*EFFE; ^~~~ make: *** [Example-mread-source.o] Error 1

Hi @Wendy723 -

If you are in the $ODE block, use SOLVERTIME (the equivalent of T in NONMEM) rather than TIME. If you really want TIME, you'd have to copy that to a new variable in $MAIN and then use that new variable in $ODE. But it sounds to me like SOLVERTIME is what you want here.

Please let me know if this does / doesn't solve the problem.

Thanks,
Kyle

Hi @kylebaron,

It worked well by using SOLVERTIME in $ODE. Thanks. I needed to make similar conditional statements in $MAIN for the initial values of the compartments. I tried to use SOLVERTIME but it gave me a similar error message as seen above, however it worked when I used TIME. I guess in $MAIN, TIME is the right thing to use instead of SOLVERTIME?

Thanks,
