    Hi all,
    I am having problems with the “create new variables from variable group” function, it does work – eventually, but takes between 40 – 60 minutes to create the variables – depending on the number of groups I select (30 – 125). Has anyone else had this problem? Is it a bug or is it just a result the computing that needs to be done? I would have thought the computing wasnt too difficult?
    Im working with a large grassland dataset c700 sites (rows) and 250 species(columns) that I am trying to define communities based on species composition.
    I have tried to reduce the noise of so many variables by joining closley associated species into single variable ‘guilds’ by performing a 2step analysis on the columns – this step works fine Im just having problems when I want to convert my ‘guilds’ to variables for further analysis.

    Any tips advice?

    Hi Michael

    You are right. It is taking far to long, and it shouldn’t. I’m looking into it now, and will get back with an update as soon as we isolate the issue.

    We have found the problem (4 missing lines of code!) and corrected it. We are now re-testing PATN and the updater etc before releasing the update as v3.11. I’ll post an announcement as soon as it is ready.

    Sorry about that. It is amazing how a year of testing still can’t test everything.

    Hi Michael

    We have fixed the problem and tested the new version. PATN 3.11 is now available as a fix update through the usual ‘File | Check for Update’ option in PATN. Just follow the updae instructions.
