[QE-users] Letter not recognized gG: error in matdyn.in

[Pooja Vyas]

Dear users,
The following is my input for matdyn.in to compute phonon frequency.

&input
asr='simple',
amass(1)=40.078,
amass(2)=28.0855,
amass(3)=15.999,
flfrc='3.5360.fc',
flfrq='3.5360.freq',
q_in_band_form=.true.,
/
6
gG 40
X 20
M 20
gG 40
R 20
X 20


On running the script I get the following error:

 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     task #         7
     from find_letter_coordinate : error #         1
     Letter not recognized gG
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%


 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     task #        15
     from find_letter_coordinate : error #         1
     Letter not recognized gG
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Can I know if anything is wrong with my input script?
