Dear Gromacs users,<br><br> I am trying to simulate a polymer crystal in gromacs, which is of monoclinic unit cell with cell parameters a = 0.805 nm, b = 1.304 nm, c = 1.948 nm, beta = 125.4 deg. my crystal consists of 4 unit cells along 'a' , 2 unit cells along 'b' and 4 unit cells along 'c' , So lengths of my box vectors are <br>
a = 3.22 nm, b = 2.608, c = 7.792 and beta = 125.4<br>For defining box for the simulations of my crystal i am using editconf as <br> <br>editconf -f input.gro -o out_box.gro -bt tric -box 3.22 2.608 7.792 -angles 90 125.4 90<br>
<br><br>Am not sure whether am I using the correct format or not ? Is there any specific method to mention the monoclinic cell for the simulations in gromacs.? <br>If i use like this i am getting the following warning:<br>
<br> WARNING: Triclinic box is too skewed.<br><br>Any help will be highly appreciated.<br><br><br><br>Regards,<br>Ramesh.<br>
