I'm trying to use the Presence feature to read in a separate Site Covar file. I am using a tab delimited .txt file, created using "save as" in Excel. I am running Presence 4.4 under Windows 7. The file seems to read in ok, as I can see it properly in the Presence data editor, but when I run a model specifying a specific site covar, I end up with the same result as the null model, with no site covariates specified. When I save the file, reopen the project, and try again, the program crashes. Any ideas what might be the issue?
