@zhen, I see that you posted your question over at ROOT error：can't run it - #2 by jdouglass … thanks for doing that! Let’s continue the conversation over there.
@soraya , sorry for the delay on this! And thanks for including your logfiles.
For the first issue (application hanging for several hours), I don’t know for sure what’s going on there. But it sounds like maybe running the application in a different directory is a workaround, so that’s something!
The second issue (“Python int too large to convert to C long”) looks like an issue with a defined nodata value in one of the activity/factor rasters. Could you verify that all of your nodata values are within the range of a Float32 (within 3.4E-38 to 3.4E+38)? If that doesn’t do the trick, I’ll refer you to the ROOT maintainer.
Let us know how this goes!
James
