[QE-users] error in hp.x

[Bin Shao]

Dear Paolo,

How do deal with this error? Switch off the symmetry in the calculation?

Best,
Bin

This kind of errors is almost invariably due to "quasi-symmetric" crystal structures.

Dear all,

I would like to learn how to use the hp.x program to calculate Hubbard parameters. I successfully finished the examples in the tutorial. But when I tried with my inputs, an error pops up as follows. I attached my input and output files for the pw.x and hp.x. It would be very helpful if anyone could have a look. Thank you in advance.

Best,
Bin
