When using 7.2.1 I tried to run the r.terraflow tool I received this message:

When using 7.2.2 I tried to run the r.terraflow tool I received this message:

I have uninstalled and reinstalled the latest version of the software but I still cannot get this tool to work. 7.2.1 and 7.2.2 were tested on two different computers that have a large amount of space and RAM.

Did the problem persist? If yes, how many pixels did you try to process?
