Dear ABINIT developers and users,

I am quite confused about the flag of "getden", though I have gone over the ABINIT doc for this parameter many times.

I do not understand the difference between positive (say, 1) and -1. In particular, what is the purpose to use a positive getden?

Could you pls explain it a bit?

The other question is that when I used getden = -1 for band structure calculation, I have the following problem

"The list of kpoints does not represent a homogeneous sampling of the BZ

Kpoint weights should sum up to one while sum_weights is 67.000"

when using abipy(developed by gmatteo) to deal with the data. I know it might be not appropriate to ask abipy question here, but I do hope you can help me to check my input for Band Structure calculations to make sure that I did not make mistakes.

Thanks,

Ben
