Hi,
When I try to import a Mascaret model parameterized with a .xcas file (such as the ones provided with OpenTelemac, say Test7/rezo.xcas), the model is not loaded by Fudaa-Mascaret (v3.6). I get the following error in the console:
java.lang.NullPointerException

However I can open the corresponding .masc model Test7/masc_file/rezo.masc without any problem.
Tested both on Ubuntu 18.04 and Windows 10 with Java 8.
If there's no solution to this problem, I'd be interested in a solution with the official QGIS plugin, even if I haven't been able to use it so far due to a lack of user manual.
Thanks in advance for your help!
