[GRASS-user] Re: Grass 6.4.2 on Ubuntu 11.10
Hi, As a follow-up on this issue, and as a person who never installed GRASS on Linux, I wanted to ask the Forum if there is a version of GRASS 6.x that will run on 32-bit system, which has a similar look to the most recent Unix interface. I installed 6.4.2 from the US Tier#2 web site of GRASS (the link gave the date of 2009) but I am sure that the interface looked archaic. It is important that the version is free of bugs since it will be used for a workshop designed for beginners. I will appreciate your suggestions. * I also installed GRASS 7 but there are issues with vector import and basic analyses.

For the NULL-task I use r.null, and for the 1-task r.reclass. But how can I simply use a rule in when calling r.reclass in a python script??? grass.run_command(r.reclass, input = in, output = out, rules = ???) /Johannes If you have floating point values, generally r.recode is more appropriate (or just multiply your floating point map by the appropriate number to make it integer).

In that case you have to first use your label as a new category value.
You can do that in r.mapcalc with the @ operator:
r.mapcalc labelmap = @categorymap
But how can I simply use a rule in when calling r.reclass in a python script???
grass.run_command(r.reclass,
input = in,
output = out,
rules = ???)

;-)
To make it easier, here's an example with r.colors that you can
transform for r.reclass:
colorrules = '0 255:255:255 \n 1 165:42:42'
grass.write_command('r.colors', map=carte_diff, rules='-',
stdin=colorrules, quiet=True)

Re: [GRASS-user] Re: Grass 6.4.2 on Ubuntu 11.10
Thank you for your input. Yes, I misspoke: I should have said that I was looking for relatively bug-free version of GRASS for Linux. I must also mention that the version of Linux installed on computers is beyond my control since it is a lab maintained by others. The version the computers are running is Ubuntu 10.10 32 bit ( https://launchpad.net/+help-soyuz/ppa-sources-list.html ). The archaic looking GRASS 6.4 came from ( https://launchpad.net/~ubuntugis/+archive/ubuntugis-unstable ): they reached this link from the following address ( http://grass.fbk.eu/download/software.php#g64x ). I realize that this is a mirror site in Europe and I think that this last link has some problematic versions of GRASS. I had Windows version (6.4) installed from this address for my class last semester and there were a lot of problems with mapcalc, gregion, and v.in.ogr. I will try finding the link for GRASS 7, which had problems so that it can be fixed. As for Linux GRASS 6.4 issue: I only typed GRASS in Terminal and GUI came up however, I will try what you suggested (grass64 -gui). Meanwhile, can anyone suggest a link for GRASS 6.4 for the version of Ubuntu I have to work with?
