[GRASS-user] Newbie Q - how do I use addons?

[Isabel Sargent]

Thank you for such a prompt response. I had read through the manual pages online (though I couldn't get the man command to work, perhaps because I'm using windows?). Those last 4 required fields have defaults, so in my question I was assuming that I didn't need to explicitly set them. Even if I do set them I get the error requiring an output. I don't think this in itself is a r.geomorphon issue, there is probably a standard way of defining an output (neither | or > work). I'm sure there must be examples on how to do this somewhere, I just can't find them.

Am I right in expecting to be able to find installed addons use the GUI? If so, where will I find them? If not, how do I define an output at the command prompt?

Sorry, the answer to my question must be somewhere but I have been searching for 90 minutes and have found nothing, please humour me.



I GRASS 7.0.0BETA2 installed on Windows 7. All looks fine. I have installed the r.geomorphon addon without any errors and have checked in the installed extensions manager that it appears to be installed. My problem is, what now?



I can't find r.geomorphon in any of the lists in the gui. If I use command line, I cannot work out how to tell GRASS where to put the output (do I have to pipe somewhere? How should I do this?). Command line is not happy with simply 'r.geomorphon dem=<name>' => 'ERROR: At least one output is required'
I'm not familiar with the addon, but typing "r.geomorphon help " in the command line gives a brief help message. And "man r.geomorphon" opens the whole manual page.
The required parameters are "dem" (input) and "search", "skip", "flat" and "dist" (numeric parameters).





Please just point me to some examples and I'll stop being so annoying!



Izzy
