Hi,
I am having some problems running epw.x for PbTaSe2. Every time the calculation gets past the gamma q point I get the following error:

I have followed the procedure from the tutorial and I'm not sure what is going wrong as the qpoints I am trying to calculate are identical to those output by ph.x. I have tried the calculation using ibrav=0 with specified CELL_PARAMETERS. The following are my nscf_epw, and epw input files for the each part of a very basic version of the calculation (not converged). I have used a kpoint grid of 6X6X2 and a qpoint grid of 6X6X2. Any insight into this issue would be much appreciated.

Issues running epw.x to calculate the electro-phonon coupling

Re: Issues running epw.x to calculate the electro-phonon coupling
Dear yq_zhao:
Could you show me your full outputs of scf, nscf, ph, and epw with high verbosity?
Sincerely,
H. Lee

Re: Issues running epw.x to calculate the electro-phonon coupling
Thanks for your reply.
I have packaged my output files in a zip package attached below, I don't know if you can see it.
I'm using EPW v.5.3.1.
I would appreciate any help in understanding this issue.

Re: Issues running epw.x to calculate the electro-phonon coupling
Hi yq_zhao,
Can you please check your "patterns.2.xml" file in "save/PREFIX.phsave" directory? In the fourth line of "patterns.2.xml" file, you may have
"<QPOINT_NUMBER>1</QPOINT_NUMBER>"
Since I see your error is starting from the second q-point, please change the number "1" to "2" as below
<QPOINT_NUMBER>2</QPOINT_NUMBER>
You also need to specify the correct number in each "patterns.YY.xml" file for the different q-points. For example, for the third q-point, you need to have
<QPOINT_NUMBER>3</QPOINT_NUMBER> in patterns.3.xml file and so on.
Please let me know if this works.

Re: Issues running epw.x to calculate the electro-phonon coupling
Hi H. Lee
I have checked ph.out file and prefix.dyn file, and found a problem that could lead to error reporting, but I am not clear that it is just not the problem that leads to error reporting. I hope you can help me check it.
ph.out
prefix.dyn2
epw.out
irreducible q point # 2 in epw.out is '0.000000000 0.000000000 -0.182648357', but in ph.out and prefix.dyn2 the q2 point is '0.000000000 0.000000000 -0.180268574'. Is this the source of the error? Do I need to re-select the qpoint of ph.in.

Re: Issues running epw.x to calculate the electro-phonon coupling
Hi yq_zhao,
When I see your output files, the lattice parameters in scf.out/nscf.out and ph.out files are different. Did you use one scf.in file to calculate phonon and another scf.in for the EPW calculation? My suggestion would be to take the same scf.in file from the phonon calculation and rerun the EPW, the problem may be solved.
Please let me know if this works.

Re: Issues running epw.x to calculate the electro-phonon coupling
Hi Gyanu
Thanks for your reply.
I followed your advice and carefully checked scf.in in phonons and EPW files. There is a problem with not using the same scf.in. and the source of the error is probably in the scf.in inside phonons. I typed noncolin=.true. and lspinorb=.true. These two parameters are missing from scf.in in the epw file.
However, the operation of epw.x did not succeed. I hope you can give me some suggestions.
