[Pw_forum] "Input ibrav not compatible with space group number"

[Yogesh Kumar]

Dear Paolo Giannozzi,

    Thanks for the reply. I am currently using v 5.1.1. Can I say that
the error  I am getting is due to older version of QE being used? If
yes, I will try to install latest version.



Thanks and Regards

Yogesh Kumar


 v.6.1 works for me either with ibrav=12 or without ibrav
