Bug report #15492

Iterative execution of algorithms doesn't work.

Added by Nobuhiko Yoshimura over 7 years ago. Updated about 6 years ago.

Affected QGIS version:2.16.1 Regression?:No

Pull Request or Patch supplied:No Resolution:not reproducable
Crashes QGIS or corrupts data:No Copied to github as #:23416


I was trying to clip dem by watersheds.
It was same process as below.


But it doesn't work when it iterates.
Without iteration, I could clip my data.
I made sure that polygon(watersheds) and raster(dem) have same CRS.

I think this function is very useful for everyone.
Please give me some idea to fix this problem.
