r.hazard.flood.py returns a ParseError

[Ddm]

Hi, I'm trying to run the r.hazard.flood.py add-on, but I'm getting the following error message. I'm new to GRASS so I apologise if this is an obvious user error. Many thanks.

Hi,

you are trying to run 'r.hazzard.flood.py', which is a typo. Correct is r.hazard.flood. Nevertheless, if i try to run r.hazzard.flood as you did, i don't get that error message. By the way, the module is an add-on written on linux platform, and AFAIK not yet tested on windows. If you are willing to test it, you are very welcome. Could you please try to run it again. And, please, download the r51053. I just found that the version online was not up-to-date.

Thanks, madi

hi,

Thanks for your help. Actually, it is not a typo: I do have to launch "r.hazard.flood.py". Otherwise I get the error message below. It is also hte name that appears in my list of modules. As a matter of fact, it is the only one that has the ".py" extension in this list.

I also updated with the latest code but I still get the same error message (the original one I mean).

yeap, the extension is required on MS Windows. Otherwise OS doesn't know which interpreter to use.

hi,

thanks for feedback. Actually the typo I meant is "hazzard" instead of "hazard". I am not able to reproduce the error because i don't have access to windows machine. Any idea from developers is very appreciated to try to solve this issue. Thanks for patience.

Hi, Ah OK... sorry for the misunderstanding. :-)

Hi,

please try r51063. If you get the error message: "grass.script can't be imported." please read ​http://grass.osgeo.org/wiki/GRASS_and_Python#Creating_Python_scripts_that_call_GRASS_functionality_from_outside in order to adjust the paths of grass variables.

Thanks, madi
