[lammps-users] Error to specify the non-orthogonal unit vector (Edges of unit cube)

Lammps user,
I am interested to specify the non orthogonal edges of unit cell. I am have taken the reference of Lattice command, but There is one problem with it the position of second basis is not correct. Even i got the collinear error when i specifiy the a1 1 0 0 and a2 -1/2 sqrt(3)/2 0, but it does not happen if i take the a2 as -0.5 0.886 0. So need your advice.

my lattice command is like bellow:

lattice custom 1.414 a1 1 0 0 a2 -0.5 0.886 0 basis 0 0 0 basis 0.5 0.2886 0

Thanking you

This command:

lattice custom 1.414 a1 1 0 0 a2 -0.5 0.886 0 basis 0 0 0 basis 0.5 0.2886 0

gives no colinear error for me when I use it.
So I'm not clear what you're asking.
