MARKMASS(1)               TIPSY COMMANDS              MARKMASS(1)


       markmass - mark particles according to their mass


       markmass box-number minimum maximum


       markmass  marks  all  the particles in box box-number that
       have masses between minimum and  maximum,  inclusive.   If
       box box-number is not loaded an error is generated.

       To  unmark particles use either the unmarkall or unmarkbox
       commands.  Remember, marked particles are  always  plotted
       in  green.   Particles  remain marked even when a new time
       frame is loaded but after a new time frame is loaded   any
       particles  that were marked in the previous time frame can
       only be unmarked using the unmarkall command.  Marked par-
       ticles  can  be written to a file using the writemark com-
       mand or read from a file using the readmark command.  Par-
       ticles can also be marked using the markarray, markbox and
       markgal commands.  Statistics about marked  particles  can
       be determined using the markstat command.
