Greetings all,<br><br>I am trying to run r.le.patch to create a map of separate 'patches' using the -c flag to drop the edges and only keep core areas of a certain size.<br><br>To recreate this:<br><br>g.region n=1 s=0 e=1 w=0 res=.01 ## Make some region<br>
r.random.surface output=surface ## create a raster to use as input<br>r.random input=surface n=10 raster_output=points --o ## create some random points<br>
r.grow input=points radius=10 output=patch --o ## grow them to make 'patches'<br>r.le.patch -n map=patch sam=w co1=2 co2=c1 ## run r.le.patch with -n flag to identify the patches by number - it works fine<br>
r.le.patch -c map=patch sam=w co1=2 co2=c1 ## run r.le.patch with -c flag to identify only 'core areas' - it crashes!<br><br>It segfaults with the error shown below. I am running the GRASS6.4.0RC5 checked out and compiled this morning on Fedora 11 2.6.30.9-90.fc11.x86_64<br>
<br>Any ideas? Am I doing something wrong or is this a bug? I've tried several settings for the co1 and c02 and it crashes with every combination I have tried.<br><br>Thanks for any help.<br><br>###########################################################<br>
