Looking at your bash scripts, I think the first thing to do during<br>
this bonding period is, as you planned yourself, to get familiar<br>
with the writing of GRASS modules in Python. You can have a look at<br>
existing scripts [1, 2] to get feeling for this works and how to<br>
structure addon code in order to make it directly installable with<br>
g.extension.<br>
<br>
You can find the actual function definitions and documentation of<br>
the GRASS Python scripting library at [3]. The functions in that<br>
library should be more than enough to translate your scripts into a<br>
(or several) modules.<br>
<br>
Be aware that GRASS modules create their own GUI. So, unless you<br>
need some interactive features in your modules, you will not have to<br>
program your own GUI.<br>
<br>
<br>
Thank you for your precious suggestions! I'll start studying how to write a GRASS module in Python in the next days and at the same time I will keep on testing the procedures so as to show you some results and fix some open points.<br>
<br>
<br>
Something else you should probably do during this bonding time is to<br>
elaborate a schema of your algorithm, so that it is easier to<br>
understand what it does at each step.<br>
<br>
<br>
Yes, this could be very useful also for me in order to better organize and put in order everything!<br>

Have you advanced on any of this ? Do you have any questions ? Please don't hesitate to ask on the mailing list.<br></blockquote><div><br></div><div><div>Yes, I started working with GRASS Python scripting library. I'm following the link [0] you suggested, I'm also looking at other existing GRASS scripts [1,2] and moreover, Roberto gave me one of his scripts as an example. I have just committed the first version of the python script I'm working on, it works and I'm quite satisfied ;-)</div><div>Tomorrow I want to elaborate the schema of the algorithm and at the same time, I have to keep testing the procedure.
