<div dir="ltr"><div><div>Dear Q-E users</div><div>I am newbie to hybrid pseudopotential calculations. While runing the calculations for my system, I always struck with this error. after searing the pwsf-archives, I came to know that the <b>nqx1 =</b> variable needs to changed. However I have tried some combinations, but every time come up with the same error. I am using Q-E 5.0.2. Can anyone help me how can I get rid of this problem.</div><div> </div><div> <b>Error in routine electrons (1):</b></div><div><b> dexx is negative!
