Should this be documented on wiki for grass7 new features, so that there is one place people where can go to when updating their scripts, workflows, edu material etc. to grass7? http://trac.osgeo.org/grass/wiki/Grass7/NewFeatures There is a change for r.mapcalc noted like this: r.mapcalc: use pthreads for parsing but it is not clear from this that every r.mapcalc expression that people have will need to be modified to run in grass7 (if I understand the changes correctly - I haven't tried it enough yet).
Or we could just say - read the manual page for everything when updating to grass7, it may be easier than trying to track all the changes Helena On Jul 17, 2011, at 12:47 PM, Markus Neteler wrote: > On Mon, Jul 11, 2011 at 7:36 PM, Michael Barton <[email protected]> > wrote: >> This is from GRASS 7 compiled from svn trunk yesterday. >> >> I'm simply trying to assign null values in an SRTM using r.mapcalc.
