Thanks for the help.
The thing with decimal separator I knowed. I actually tried to use on a computer where the “.” is the decimal separator, but it happens the same thing.
About your other tip, about files on database, I didn’t really understood:/
I’m trying to do this right now, but a new error appears (http://hec-ras-help.1091112.n5.nabble.com/Error-on-Loading-Terrain-Ras-Mapper-td3175.html;cid=1477275005278-451)
