Hi, I'm running QGIS 2.4.0-Chugiak on a Windows & machine, and I'm new to QGIS.
I'm trying run a model that has three algorithms, two of which are run in
"parallel" and a third that uses the outputs from form the first two. I
specified that that third The first algorithm runs fine but when it gets to the
second it bombs with the message:
C:\PROGRA~1\QGISCH~1\bin>exit
Converting outputs
Outputs: outfile =E:/temp/PreNBR7.tif
OK. Execution took 49.503 ms (1 outputs).
Prepare algorithm 1: r.mapcalculator - Calculate new raster map from a
r.mapcalc expression.
[Errno 9] Bad file descriptor See log for more details
The three pieces work fine when broken into separate models but I would like to
have the whole thing run in one go..
I exported to a script (below) and have attached the model.
##test_dnbr=name
##rasterlayer_prenir=raster
##rasterlayer_preswir=raster
##rasterlayer_postnir=raster
##rasterlayer_postswir=raster
##outfile_alg0=output raster
##outfile_alg1=output raster
##outfile_alg2=output raster
outputs_0=processing.runalg("grass:r.mapcalculator", rasterlayer_prenir,
rasterlayer_preswir, None, None, None, None, if((A+B)==0,0,1000*(A-B)/(A+B)),
None, 0.0, outfile_alg0)
outputs_1=processing.runalg("grass:r.mapcalculator", rasterlayer_postnir,
rasterlayer_postswir, None, None, None, None, if((A+B)==0,0,1000*(A-B)/(A+B)),
None, 0.0, outfile_alg1)
outputs_2=processing.runalg("grass:r.mapcalculator", outputs_0['outfile'],
outputs_1['outfile'], None, None, None, None, A-B, None, 0.0, outfile_alg2)
Any suggestions are welcome,
