I think you mean the .restrt file that is generated by a sander minimization
prior to calling nmode here.

If you set "ntxo = 1" in the function create_nmode_input in the file
mm_pbsa_createinput.pm, you will get a formatted .restrt file. To use this
for further nmode calculations, you also need to set "ntx = 1" in the same
function.
The reason why a binary .restrt file is output is that using the formatted
version instead reduces the precision in the atomic coordinates, which will
have an influence on the gradient.
