Hi Girma,
xanim is not needed by PRECIS. It allows for the monitor window plots to be animated, but it has absolutely ZERO
affect on the model run or capability.
That said, if you really really want it installed, download the appropriate rpm corresponding to whatever
distribution of Linux you are using and the CPU (either x86 or x86_64 for 64 bit linux).
Code:

The same is true for the plots that appear in the Monitor Window. If they don't appear, it is not a big deal. As long as the model is still running, that is the important thing.
Thanks
David
