EPW break when set longrange=.true.

[jack]

Dear,
I want to check the impart of longrange, shortrange and lpolar tags.
The input files are obtained from the tutorial Files of Summer School 2024. The system is BN. And I add the prtgkk tag and shortrange (or longrange) tag to obtain the ep vertex. The lpolar=.true. and shortrange=.true. works well, while longrange=.true. bring an error message:
Error in routine readin (1):
Bad line in namelist &inputepw: " longrange = .true." (error could be in the previous line)
The inputs of EPW is listed as below. The version of EPW is 5.9.

Dear Jack,

Could you try setting 'longrange_only = .true.' ?
At the EPW website there might be a mistake regarding that variable.

Best,

Nina.

Dear,
Thank you for your response. EPW works well after I change the 'longrange' to 'longrange_only'. I want to ask another question about epw.
If I set 'longrang_only', only the longrange part of e-ph is considered.
If I set 'shortrange', only the shortrange part of e-ph is considered.
If I set 'lpolar' only, both the shortrange and longrange part of e-ph are considered.
Is right?
