color=#0000ff size=2>If you are looking for the actual commands to make picks
look in the command listing for plotpk for all the options. Just place your
cursor on where you want to make the pick and then type in the desired
attributes. Usually you have (e)mergent or (i)mpulsive, (u)p or (d)own, quality
(0,1,2,3,4), (p)wave or (s)wave. The letters or numbers in parenthesis are what
you would type. Once you are done it will show you your pick and label it.
Re-pick by moving the cursor and typing it in again.</FONT></SPAN></DIV>
