Hello,
I found that each time I launch a simulation macro I get the following error:

Error in <TList::AddLast>: argument is a null pointer

I tried to backtrace the problem and I found that it happens when one use the pipe (CbmPipe). I tried to take a look into the code but there is maybe something connected to cbm that gives this message ("pipevac1"...), I do not know.
In each case the message happens before the:

fSensNodes->AddLast( aVol );
fPassNodes->AddLast( aVol );

line, so it is connected to something else.

Can somebody investigate on it? In each case the pipe is inside "passive" directory, so in between the common packages -> it cannot be touched by us.

Thanks

The passive directory belongs to pandaroot and not to the
base classes, so you can change whatever you want.
It even must belong to panda otherwise cbm and panda must
use the same pipe, target etc.

Ciao

Ok,
I found the problem and corrected it.
In the latest version of svn you can run the simulation without that error.
Bye
