<div dir="ltr">Hi Abid,<div><br></div><div>If you look in the manual (I'm looking in the 3.1 manual, but I'm sure it's the same in 2.1), the "use_bloch_phases" tag cannot be used with disentanglement. You are asking for 22 wannier functions, but inputting 32 bands. Therefore, disentanglement is required. If you want to use the "use_bloch_phases" tag, I recommend using "exclude_bands" during the vasp2wannier step to remove unwanted bands (e.g. conduction bands) that you do not expect to be important.</div><div><br></div><div>Best,</div><div>Peyton Cline, PhD</div><div>Postdoctoral Researcher</div><div>Eaves Group</div><div>Univ. of Colorado, Boulder</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Jan 23, 2021 at 12:43 AM Abid Rehman <<a href="mailto:rehmanustc@gmail.com">rehmanustc@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><img src="cid:ii_kk9em1rw0" alt="wannier-win.PNG" width="539" height="542"><br><img src="cid:ii_kk9emahf1" alt="error.PNG" width="542" height="473"><br>Dear Wannier90 users,<div> Presently, I am learning VASP and Wannier90 packhages.In this context, I have successfully installed vasp5.4.4 and wannier90-2.1.0 on our system and also have interfaced with each other. It works successfully to generate the input files such as wannier90.win and wannier90.mmn etc. It also generates a wannier.amn file(i.e projection file) when <b>num_wann=num_band</b> (i.e when there is no disentanglement). But it gives an error to generate a wannier90.amn file when <b>num_wan < num_bands</b> (i.e in case of disentanglement ). The error is like this =><b>Error: Cannot use bloch phases for disentanglement. </b></div><div>I don't know how to resolve this issue. I need your kind help in this regard.
