At first glance, it looks like there is a problem with data import. If you are able to see the imported bands clearly within GRASS, then there could be problems with the signature collection process. Your current output looks like the row numbers have been classified instead of the data values

[GRASS-user] minimal wxPython version

2013-03-19 Thread Anna Kratochvílová
Hi all, I would like to change minimal required version of wxPython [1]. Currently we support (theoretically) version 2.8.1.1 (released 2007). I suggest to change it to 2.8.10.1 (2009), for example 2.8.10.1 was shipped with Ubuntu 10.04 LTS. The reason is obvious: wxGUI is limited by this

Please email to the group so that you get additional responses. I do not think you need to group the rasterized training data with the Landsat image group. Use i.group to define the group and the subgroup. You need to also check how many pixels are within each training polygon. If you have only

I think that this is a good idea for GRASS 7. We shouldn't really do it with GRASS 6. I like going to at least Python 2.5 also. Michael __ C. Michael Barton Director, Center for Social Dynamics Complexity Professor of Anthropology, School of Human Evolution Social

I was not able to get a working implementation of GRASS 7 for Mac. It also seems to have broken my 6.4 installation; something about the python framework throws errors now. I am installing a VM of Ubuntu so I can try it out in a different environment. I'll update if I get it working.
