I wanted to know how to take many multi-band (RGB) files in a folder and extract a single band from each one, putting everything in an output folder with the single band transformed files.

How should I proceed without extracting every single file?

  • IMHO you can approach any single step instead of a complete application. Any single step already documented in SE – Luigi Pirelli Feb 28 at 16:27
  • btw do you ned pyqgis or just create a agis batch process suing processing or a processing model? – Luigi Pirelli Feb 28 at 16:29
  • No, I did not create any pyqgis scripts yet, but I was looking in the forum and I found a lot of confusion. Can you help me? – vins_26 Feb 28 at 18:13
  • According to the rules of this website, if you're asking for help with coding you must include a coding attempt. Therefore this question will be closed as off-topic. You can make it it eligible for re-opening by editing the question to either (1) include a coding attempt, or (2) request a non-coded solution. – csk Mar 1 at 18:15
