Even when I use the resampled DEM, i.topo.corr still creates maps with null cells at the edge... Here is a sceenshot <http://i.imgur.com/ieZR20u.png> from mapswipe. After digging a little bit deeper it seems that the created maps have null cells <https://gist.github.com/pmav99/c7f61d82cba126df722a#file-univars-sh-L3> at the borders of the region.
I 've updated the script <https://gist.github.com/pmav99/c7f61d82cba126df722a> if anyone wants to check. cheers, Panos
