Re: Coordinates of prototypes and replicas

Hi Makis
Sender: owner-fluka-discuss_at_mi.infn.it

This info is not in a common but you have to do the transformation calling the
subroutine DOTRSF

       SUBROUTINE DOTRSF ( NPOINT, XPOINT, YPOINT, ZPOINT, KROTAT )

Set NPOINT=1, KROTAT=index of your transformation and XPOINT, YPOINT, ZPOINT
to the point which you want to transform.

Be careful, XPOINT, YPOINT, ZPOINT are both input and output variables, i.e.
the original value will be overwritten in DOTRSF. Thus, save the original
coordinates first on a local variable and use them in the DOTRSF parameter
list.

Hello,

I have a geometry based on the use of LATTICE cards with the
corresponding ROT-DEFI cards. When looking for the x,y,z coordinates of
a particle from (TRACKR), I get the absolute coordinates of it. What I
would like to have access to, is to the equivalent "prototype"
coordinates. Is there a way to get this information out from some common
block?

Thank you in advance,
Makis
