here goes my mdp file.The when i attach the top file by mail is
getting bounced back.Thanks in adcvance

Fatal error:
48 of the 46602 bonded interactions could not be calculated because
some atoms involved moved further apart than the multi-body cut-off
distance (1 nm) or the two-body cut-off distance (1 nm), see option
-rdd, for pairs and tabulated bonds also see option -ddcheck
