Hey<br>
<br>
I have tried Glynn's solution like this:<br>
<br>
r.mapcalc "$GIS_OPT_COUNTER= float(0)"<br>
<pre wrap="">tmp=tmp.myscript.$$</pre>
for opt in $GIS_OPT_INPUT; do<br>
r.mapcalc "$tmp = $opt + $GIS_OPT_COUNTER"<br>
g.rename rast=$tmp,$GIS_OPT_COUNTER<br>
done<br>
<br>
And I got<br>
<b><i>syntax error, unexpected ',', expecting $end<br>
Parse error<br>
raster <tmp.myscript.724> not found</i></b><br>
<br>
I changed myscript to r.ndviserie<i><b> </b></i>(myscript filename)
and i got this:<br>
<i><b>syntax error, unexpected ',', expecting $end<br>
Parse error<br>
raster <tmp.dwe.ndviserie.3692> not found</b></i><br>
<br>
It seems that he is not recognizing tmp as a file where to store an
image. <br>
yesterday I found a reference of initializing TMP files with a
"r_fillnulls_". I try to find this function, or any reference to this,
but nothing was found. What is this?<br>
<br>
Thanks Glynn and everyone else<br>
<br>

You are absolutely right. I made a mistake copying the expression.
Here it goes:
#itinialization of counter1
r.mapcalc $GIS_OPT_COUNTER1= "float (0)"
The cycle:
IFS=,
for opt in $GIS_OPT_INPUT; do
r.mapcalc $GIS_OPT_COUNTER= "$opt+$GIS_OPT_COUNTER"
done
</pre>

Don't use the same map as both input and output. Instead:
tmp=tmp.myscript.$$
for opt in $GIS_OPT_INPUT; do
r.mapcalc "$tmp = $opt + $GIS_OPT_COUNTER"
g.rename --o rast=$tmp,$GIS_OPT_COUNTER
done
Although for this specific task (adding a list of maps), use
"r.series ... method=sum".
