[Chimera-users] Supersample

[Tom Goddard]

Hi Hernando,

  You do not need a "wait" after each "reset pN 1" command.  There is an 
implicit "wait 1" after each reset command and also after other commands 
(e.g. turn, move, repr...) that change the display.  You also don't need 
the "1" in "reset pN 1" -- it is equivalent to "reset pN".
