[GRASS-user] Georectify images- question
Hi there Sorry for making this question but: In Georrectify module (wxPython) the source refers to what: Data that is already georrectified or data that I want to georrectify? Thanks Kat ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
[GRASS-user] Georrectify- create a group with the newly georrwectfied images
Greetings I have used georectify (wxGUI) and I have one suggestion (or question): is it possible to create a group of the newly georrectfied images? Instead of just creating them, it would be a good idea to create that. If so, How can I do that? (i mean, where shall I start working) Thanks Best regards helena ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
[GRASS-user] Python script- drop-down menu list of multiple groups
Greetings I'm implementing a Python Script and I need to know one thing related with Modules Interfaces: can I have a drop-down menu list of multiple groups? Instead of just selecting one group (e.g. i.maxlik) select more than one (multiple)?

Re: [GRASS-user] Another script question
Glynn - many thanks!

That way, if I run a script overnight and a Grass-GIS process fails, I at least know there's a problem! If either of the files $HOME/GIS_ERROR_LOG or $GIS_ERROR_LOG exist, errors and warnings (but not messages) from GRASS commands will be written to that file. Or you can just capture all output from any command (including a script) by appending logfile to the command. ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

[GRASS-user] SVN problems
Hi all, I'm trying to checkout the code from SVN but when I issue the command svn checkout https://svn.osgeo.org/grass/grass/branches/develbranch_6 grass6_devel I get the following error: svn: OPTIONS of 'https://svn.osgeo.org/grass/grass/branches/develbranch_6': could not connect to server (https://svn.osgeo.org) Is it me?

Re: [GRASS-user] Problem with GRASS 6.4RC6 and wxPython 2.8.11 on CentOS 5.5 x86_64
there are more fixes in releasebranch_64, try to compile code from SVN [1].
Sorry that it took me so long to come back to you.
I tested the revision 43144 of releasebranch_6_4, and the problem is
indeed solved!
The only significant modification I had to do in our spec file was
that a ChangeLog_%{version}.gz file was missing.
I guess that it is only available in releases tarballs but not in SVN, isn't it?
RPMs for i386 and x86_64 containing a build of this revision are
available in the ELGIS Testing repository (elgis-testing):
http://elgis.argeo.org
Thanks a lot for your help!

Oh... :-O. Shell script(ing) ability completly removed in grass7x? You can still run GRASS commands from shell scripts, and you can still use g.parser in shell scripts. I have tried but get GRASS 7.0.svn (nc_spm_08): sh i.fusion.his sh: i.fusion.his: command not found Does it have the execute bit set? If it doesn't, g.parser can't execute it.

Often it is so much faster to work in the shell... I've been sort of out the dev loop for several months, but I'm pretty sure that 'lack of shell-script support' means that shell scripts are not currently recognized by the interface parser. That means that a shell script invoking GRASS will not produce an automatically generated wxPython GUI window. That is incorrect; g.parser still works with shell scripts.
