[Sohail Ahmad]

Dear QE users

I am unable to understand the reason behind error #19
Kindly help

http://www.quantum-espresso.org/wiki/index.php/Citing_Quantum-ESPRESSO

     Current dimensions of program PWSCF are:
     Max number of different atomic species (ntypx) = 10
     Max number of k-points (npk) =  40000
     Max angular momentum in pseudopotentials (lmaxx) =  3
     Waiting for input...
