<BODY>I am looking for a perl script that can average small groups of numbers down columns (i.e. 50 out of 500 numbers). I know this is a simple thing to do but I am a new user and have been having problems with it so if you have a script that I could use or that might be a good reference please let me know. thanks.<BR><BR>Damion Nero <BR>Coruzzi Lab <BR>Department of Biology <BR>New York University <BR>766 Waverly building <BR>New York, NY 10003-6688 <BR>Tel: (212) 998-3963 <BR>email: dcn208@nyu.edu <BR><BR><BR></BODY>
