The FINDSYM code (http://stokes.byu.edu/iso/findsym.php) takes as input a primitive or conventional cell and returns the primitive cell along with the Wyckoff positions, space group and primitive lattice vectors/constants.

In input script you have given conventional unit cell, and all calculation in pwscf are done via primitive unit cell. How i can get to know that calculation are done via primitive unit cell? What are the points in input file that can change unit cell from conventional to primitive? Can you please explain little bit more? So in output script it is primitive unit cell. No need to worry, just take optimised coordinate from out put... Thank you.

Because in my case its happening. For the reference, I am attaching the input and output images of the unit cell. Please have a look.
