[Qgis-developer] Creating script (conflict with python/Grass + wrong folders)

[Davide Sponchiado]

Hello everybody,
it's my first mail and I hope you can help me.

In the past year I create (with other people) 3 scripts connecting QGIS 
with Hec-RAS.
The problems started when to check to behaviour of the original program, 
I installed ArcGis in the same pc. From that moment, I started to have a 
lot of problems (freeze first of all in GRASS and in QGIS, than problems 
in deleting files in GRASS) and i saw that not all the programs worked 
in the right way.

So I worked all this period in a Virtual Machine with only QGIS/Grass 
inside it. I created the script in QGIS 2.0 and everything worked ok 
with following versions. But always inside the Virtual Machine.

On the main machine, I saw that the great problem is that in the output 
file (a .sdf which is like a txt) there is a "start new paragraph" for 
some lines. I've done the same path with python in GRASS and everything 
works fine.

Can you confirm that there're conflict between pythons installed with 
different programs?
(I've got a lot of troubles to uninstall Arcgis and to uninstall and 
reinstall Qgis because there are a lot of pieces around the pc.. many of 
them I deleted in the regedit too but I'm not sure to have done all the 
work).

Is is right to put the python file inside the QGIS\bin folder meanwhile 
the txt file (the algorithm) inside the 
...\QGIS\apps\qgis\python\plugins\processing\(algs\)grass\description 
folder?

Thanks for the help
