    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
