about the 2nd order force constants in quantum espresso format

[ybC007]

Dear Dr. Tadano,
Hello,
I found that alm provides the 2nd order force constant in the quantum format, but the tag is not shown in the manual. I try to add
the FC2_QEFC tag in the input file to get the .fc file. The format of the .fc file seems to be different with the result generated by q2r.x.
This maybe a deprecated feature? Or it's just a bug?
Thank you very much in advance!
Looking forward to your kind advice.

FC2_QEFC is still not supported. Only tags listed https://alamode.readthedocs.io/en/latest/almdir/inputalm.html#list-of-supported-input-variables are supported.
