PURPOSE

UUSAGE:    PDB SH
         
          .PDB INPUT FILE: abc.pdb
          [Enter the name of the PDB file to be shifted with extension 'pdb'.] 

          .PDB OUTPUT FILE: def.pdb
          [Enter the name of the output PDB file with extension 'pdb'.] 
   
	  .X, Y, & Z SHIFT IN ANGSTROMS: 100, 200, 300
           [Enter X, Y, Z shift (Angstroms)in SPIDER coordinates. If your 
            shift is in units of pixels, multiply it by pixel size.] 

NOTES	    1. The program changes the shift into PDB format, and then 
	    applies the shift operation to PDB coordinates:  
a. Change the coordinate system
SX = SYT
SY = SXT
SZ = -SZT
b. Apply shift operation to PDB coordinates
X = XO + SX
Y = YO + SY
Z = ZO + SZ
2. This operation does not change the format of a PDB file. 3. Implemented by Zhong Huang, Pawel A. Penzcek. SUBROUTINES: PDB CALLER: DRIV1
