[Gate-users] Problem in MaterialDatabase

Hi Smita , 

I believe you're following the Material section of this http://wiki.opengatecollaboration.org/index.php/UsersGuide? 

The messages states that the file named MyMaterialDatabase.db can't be found in the current directory (where you execute the app). 
Do you actually have a file named MyMaterialDatabase.db?
This file should be inspired (or even simply duplicated) from the GateMaterials.db file you can find in the examples ( see file attached).    

For whatever material you want to use, you need to define it in your material file (no matter how you name it) with the proper name and directory reported in your macro. 

Hope this helps.
