This is probably not given in any outputfile, If you use 5 points for the E v/s c/a plotthe output in the w2web plot c/a window should be something like (note works only for 5 points, but you may reduce to 5 by deleting or renaming the scf files where the points arer too far away from the minimum

Dear Tomas Kana, Thanks a lot for your replay. But according to your suggestion I have tried : grep :LAT case.scf | tail -1 But from this command is giving the lattice constant of my last structure file. As I have given the c/a ratio from -4% to 4% in steps of 0.5, using your command I am

Dear Prof. Blaha and Wien2k users, I'm doing optimization for a Hexagonal system with varying c/a and with constant volume (option 2 as per User Guide from the option x optimization) But I could not able find out the optimized c/a ratio. I have used the option to plot the graph E vs
