That's a bug in r.flow:if (!((region.ew_res == hd.ew_res) && (region.ns_res == hd.ns_res))) G_fatal_error(_("Elevation file's resolution differs from current region resolution"));
Try the attached patch. It replaces the exact comparison with a check that the resolutions agree to within 1ppm.
Glynn, Perhaps I've specified the region incorrectly, but the patch makes no difference. Upon invoking GRASS I run 'g.region rast=aber5m res=5 -ap' followed by 'r.flow elevin=aber5m aspin=aber5aspect flout=aberFlowline lgout=aberFlowlength' and immediately see: ERROR: Elevation file's resolution differs from current region resolution I'm surprised this issue's not come up before.
