Dear all,

I have used set abc box command many times but never faced this problem before.

command is: set w1 box {188 191 166}


earlier I used to get box angles 90 90 90 in inprcrd and prmtop but I am not getting it now as shown below.

my *.prmtop shows this

%FLAG BOX_DIMENSIONS
%FORMAT(5E16.8)
  0.00000000E+00  1.88000000E+02  1.91000000E+02  1.66000000E+02


my *.inpcrd shows this


 188.0000000 191.0000000 166.0000000   0.0000000   0.0000000   0.0000000



1) Please suggest if I am missing something. Also I am not able to get how earlier it recognised 90 90 90 angles as I just used set box (means not defined oct or cube box)


2) Or as a last resort I should modify manually the prmtop and inpcrd file like this (is this ok or something else more should be modified...)


inpcrd

 188.0000000 191.0000000 166.0000000   90.0000000   90.0000000   90.0000000

prmtop

9.00000000E+01  1.88000000E+02  1.91000000E+02  1.66000000E+02



thanks,
Jiom
