<meta http-equiv="content-type" content="text/html; charset=utf-8"><div>Hi,</div><div>Some algorithms in the processing tool box rely on software that in not installed on Qgis. It seems that this is the case with Orfeo toolbox.</div><div><br></div><div>First, find and install the software on the net. Orfeo Toolbox is open source. Then, click on the processing menu in Qgis and you will see the options (settings, options, or configuration (I am not in front of a screen)) to set the directory of the binaries (normally the .exe file). Once this is done, you will be able to use the toolbox. Close and reopen this directory screen to make sure it saved the directory properly. </div><div><br></div><div>You can also do that in Qgis without Orfeo (but Orfeo is very good). In the Qgis raster menu, you will find the gdal translate function. Select the input file, the output file and the rest of the options. You will see on the bottom of the window the gdal script that is modified as you fill in the options. Then click on the small yellow pencil and then finally on the help button. That will bring you to a web page where you can see options that are not in the Qgis gui. Add the -b switch to the script. If you add "-b 4" (no quotes) you will save band 4 only. See.</div><div><br></div><div><a href="http://gis.stackexchange.com/questions/62133/how-to-export-only-one-band-from-an-image-using-gdal" target="_top" rel="nofollow" link="external">gis.stackexchange.com/questions/62133/how-to-export-only-one-band-from-an-image-using-gdal</a></div><div><br></div><div>I Imagine you can also do this in the processing toolbox. If you right click on the algorithm , you will see the option to script the function multiple times. This way, you can set the scripts so that, if you have 10 bands, you can set all 10 output files. That will save you time. There should be a space where you can add additional switches. Add the -b 1 in the there then -b 2 for the next file... Once you have set up everything, Qgis will save all the files in one shot.</div><div><br></div><div>Good luck</div><div>Nicolas</div><div><br></div><div><br><br><div>Envoyé de mon iPad</div></div><div><br>Le 10 sept. 2016 à 01:42, Geraud C.
