1. PRINT OPTIONS

There are two PRINT OPTIONS, as follows:-

PRINT OPTIONS
-------------
Y    <- Produce a colour PostScript file (Y/N)?
P    <- Orientation of plot: (P)ortrait or (L)andscape?
0.0      <- Rotation angle (clockwise) for final plot

Description of options:-

Produce a colour PostScript file (Y/N)? - The first option defines whether a colour or a black-and-white PostScript file is to be generated.

Orientation of plot: (P)ortrait or (L)andscape? - The second option defines whether the orientation of the plot on the page is to be Portrait or Landscape.

Rotation angle for final plot - This parameter defines an angle through which the final plot is to be rotated. The default value is 0.0 degrees and the program generally tries to align the plot as follows:-

In Portrait mode, the ligand is drawn down the page - with its lower-numbered residues or atoms at the top, and higher-numbered ones at the bottom.
In Landscape mode, the ligand is drawn from left to right across the page.

Having run LIGPLOT and seen the final plot, you may like to rotate it through some angle. Enter the required angle here and run ligonly on the ligplot.pdb file. Remember to change the angle back to zero or the next plot will be similarly rotated.
