Hello Mina,

The most obvious reason is that the symmetry finder within Abinit didn't find the symmetries. Without knowing how you defined your atomic system, it is rather hard to tell you why. I suggest to read the documentation of the nsym variable. If you leave it to the default value, all the atomic coordinates have to be specified with a high accuracy.

Kind regards,

Alain
