Since there is no semi-colon in the command, what is grass trying to
tell
me?
Perhaps that a '\' is missing after the equal sign? Hermann
Hermann,
On the command line there is no \n; that's the way the text wrapped in the
MUA. But, I'll try it again and see if it does wrap and I'm missing that it
does.
You could also try an alternative (ternary) notation:
"weight = tan_curv_5.lm < 0 ? -100 * tan_curv_5.lm : tan_curv_7.lm < 0 ?
-100 * tan_curv_7.lm : tan_curv_11.lm < 0 ? -100 * tan_curv_11.lm :
0.000001"
