[Pw_forum] overlap of atoms

[Payam Norouzzadeh]

Hello Espresso users
I have checked the structure I want to relax it by Xcrysden and Jmole and
there was no overlap between atoms but Espresso leave
an error message  like : overlap between atoms 1 and 5, 2 and 6 ,....
Could someone please have a look to my input file and let me know how can I
fix it?

Best regards,Payam Norouzzadeh
