Lee and Mark,
Thanks for your posts I have used these comments to improve my stress problems on vegetation analysis as well with similar high stress levels as what you were experiencing. 😀
Mark were you able to export your data and run it through the Fidel program set up by Mike Bedwood using the windows verson of PATN? The program I found on the web at http://www.emilythecamel.com/projects/patn/ only uses the dos version files. As I would like to perform this anaylsis on my data.
