Larry and John
    Larry, I don't mind sending you the code. However when I write or modify
code the last thing in the process is documentation and user friendlyness :-} .
I somewhat agree with John wrt modifying data. I use the filtered data in my
triggering routine but when the trigger has been set I record it all. On another
line of thinking, wouldn't one have similar trouble recovering data after exotic
analog filtering?
     Long ago and far away I was wanting to place a remote sensor in a non
functioning gold mine (with permission)  near my house or in a remote site in a
national forest.  I therefore was concerned about storage and power.  As a
consequence I have been working on an elaborate trigger routine to only save
events I was able to catch, (kind of like fishing I guess). With available data
cards that store several megs of data, and the possibility of modems and maybe
the internet, working about storage space and trigger routines maybe academic
now.

Regards
Barry
