   Dear Subrata,
   It  needs  to do spatial calibration if you want to measure the actual
   unit. There is function called "set scale". First you should observe a
   standard  scale with known distance under microscope. Then measure the
   pixel  number  of  a  line  with  known  distance.  Using  "set scale"
   function, input actual length, unit, choose "global" option.
   There  is  also  a  plug  in  that  you  can  download.  It  is called
   "microscope  scale". So you don't need to calibrate everytime when you
   start the program.
