AMBER: regrading interaction energy calculations

Hello Amber users

I am using Amber 9 , while using the anal module for calculating the
interaction energy betweeb two residues i am getting *********** at some
places instead of the energy values in the output file ,

what is the reason for that ?

I want to calculate the interaction enrgy between a particular pair of
residues but i found that it was actually calculating for all the atoms , IS

I was getting an error sometimes "number of non bonded interactions are
more than the maximum range" but when i removed some of the atoms manually (
like if i used a coordinate file which is not having any water, in that I am
not geting the same error) even when I am using the same residue for
calculting the interaction energies in both the cases .

Energy values are given in terms of some groups in the ouput file, I think
these groups corresponds to the residues which i mention in the input file
ie 43 and 50 but if that is the case than how come there are 3 groups??? ,
it should be 2.

I am attaching my input and output files please have a look, I will be very

Thanks & Regards
