Dear all
I am using the wannier90.x interface in Yambo to interpolate the GW bands. The DFT interpolation requires many bands (say 300), so I split the GW calculations into several parts (nine, in particular), and then merged the different ndb.QP databases via ypp -q m. I found that ypp does not merge the nine starting databases into a single one, but into several, named ndb.QP_merged_1_gw_ppa, ndb.QP_merged_2_gw_ppa, ... This must be related to the sizes of the original databases, I guess.
After that I launched ypp -i + ypp for the GW eig file, but I was unable to make the code find the merged databases. As much, I could add a few corrections by renaming one of the ndb.QP_merged... to ndb.QP, but the others were completely skipped. So my questions are: is there any way to make ypp merge QP databases into a single one, regardless of their sizes? If not, how can I tell ypp what the merged databases are?
Thanks a lot in advance. Take care
Juanjo

Re: QP databases from merging
Dear Juanjo
it can be a bug in the merging part of the code, I'm checking it, and make you know
in the while, may post the GW input file you used for the calculations

Re: QP databases from merging
Dear Claudio
Thank you very much for answering.
It is something strange, because ypp merges databases into a single one when I split the GW calculations into several bands ranges. But it merges individual databases into three ones if I split into kpoints ranges. I had to do the latter to make compatible the Yambo and Wannier k-points grids.
I do not know what files do you need exactly. I am attaching the GW input and a couple of report files, and the ypp input and report files for merging. Please, let me know if you need anything else.
Thanks again. Best

Re: QP databases from merging
Dear Juanjo
I fixed this bug in the last version of Yambo on github
Version 5.0.0, Revision 19641, Hash b4c0e57ea
let me know if it works

Hi, Claudio
Sorry for the delay, but I had some troubles updating yambo to the 5.0.0 version. I checked the merging switch, and everything seems fine now. Thanks a lot!!
