AMBER: How to set Bondi Radii using xleap

Dear All,

Is there any way to set the bondii radii to zero or any value for a
specific atom type using xleap? I do it manually, and I was wondering if I
can do it using xleap somehow.

Another question is the following: When the bondii radii for a specific
type is set to zero, and igb=2 is used, I am getting NaN results in the
output file (when bondii radii is not zero - even when it is very close
to zero - the result is ok). I was wondering why this is creating a
singularity in the system when implicit solvent is used. Thanks in
advance.

Best,
