Markus,

r.param.scale in=dem_10m out=tancurv5 size=5 param=crosc
r.param.scale in=dem_10m out=tancurv7 size=7 param=crosc
r.param.scale in=dem_10m out=tancurv11 size=11 param=crosc
r.mapcalc "weight = if(tancurv5 < 0, -100 * tancurv5, if(tancurv7 < 0, -100
* tancurv7, if(tancurv11 < 0, -100 * tancurv11, 0.000001)))"

/*  The r.mapcalc command is on a single line; wrapped here. */

r.mapcalc "dem_10m.acc.w = dem_10m.acc * weight"

   With the Spearfish data set, correct? I could extract my data (dem_10m)
and send that for testing purposes. I'm using 6.5svn.
