[Pw_forum] Error in routine potinit (1): starting and expected charges differ

[Sunetra Das]

Dear QE users,

Recently I tried to make a 'bands' calculation on my system but running
pw.x on QE 5.0.3 version is giving me the following error:


*Error in routine potinit (1): starting and expected charges differ *
I had carried out a 'scf' and a 'nscf' calculations on the same system eith
the same pseusopotential file, but have not faced any error.

My input file is as follows:

Can anybody please point out where lies the fault in my input file?
Thank you.
