It seems that the nmode calculation failed and, thus, values for the
translational, ... entropies are missing for mm_pbsa.
My guess is that your system might be larger than what is considered the
default when compiling nmode. Comment the line "unlink $nmodeout;" in
mm_pbsa.pl and restart your calculation. Then check the
nmode.XXX.YYY.out file for error messages.
