I can not use Bottom Composition and Sidescan Mosaic modules in the demo project that comes with the trial version, please help!

Hi Luca,
The demo workspace does not contain any sidescan or bottom hardness data, but you can trial these features when using your own data.

Hi, thanks for the quick response!
I tried to use my own data taken with Humminbird 999 SI but I have the same problem
I try importing from my pc tracks in .gpx format and printscreens in .dat format ... may this problem be related to the format of the files or the location?

GPX format contains depth and position data only - no sonar imagery, so no sidescan and no bottom composition data. If you want to test these features you need to import full sonar logs, which for Humminbird means .DAT files and associated .SON files (ReefMaster will find and load the .SON files automatically, so long as they are present in a folder with the same name as the DAT file).
