Hello Bo Liu,

please post to the forum, as most problems are of general interest, and their solutions even more so.

I'm afraid that we're not in the solution case here, though. The symops found off the bilbao server and in abinit are slightly different (sign changes) but I don't know why. It could be a cartesian - reduced coordinates problem, but I can't tell.

I had sent a version of get_irreps which also tried the cartesian symops if the reduced ones didn't work, but the abinit distribution appears quite out of date, even tokenize_file.py has dissappeared. I don't have time to go dig it up, but I believe I sent it to the mailing list as well. Please check this, or you can play with the routine get_sym_corresp in get_irreps.py

Matthieu,

In v5.2.2, tokenize_file.py is located in util/misc . Maybe it was not
realized in the v4 to v5 transition that it should be in the same directory
than get_irreps.py (i.e. extras/post_processing) . Can you confirm ?

Rgds,
Xavier
