The Select Data button opens the following window:
The Select Data button is used to load data into QRev. QRev can load data from the following three sources:
1. SonTek RiverSurveyor Live (RSL) Matlab output (*.mat),
2. TRDI WinRiver II (WR2) mmt (*.mmt) and pd0 (*.pd0) files, and
3. Matlab file saved from QRev (*_QRev.mat).
Clicking the appropriate data type will open a file selection dialog.
NOTE: The user cannot add files to an existing QRev session; all files must be loaded at the same time.

For RSL measurements, moving-bed tests and transects must be exported from RSL using the MATLAB export feature. These files must be output using east, north, up (ENU) coordinates and BT, GGA, or VTG track reference. The files selected by the user from the Open File window shown in figure 6 should include the *.mat files for all transects in the measurement (Windows commonly does not display the file extension and considers *.mat files to be Microsoft Access Table Shortcuts.). QRev will automatically load associated moving-bed tests, system tests, and compass evaluations provided they follow the standard RSL naming and file storage conventions. Moving-bed tests filenames must begin with “Smba_” or “Loop_” and be exported to the MATLAB format (*.mat). The system tests and compass calibration must be stored in subfolders of the measurement folder and be named System Test and CompassCal, respectively.
For TRDI ADCPs, select the *.mmt file in the Open File dialog and the transects and supporting data will be loaded. To only load the transects that have been checked in WR2, first click the “Checked Only” box and then click on TRDI.
The QRev data type is for a measurement that has already been processed and saved by QRev. The file is a “*_QRev.mat” file. This file contains all the data and settings used in QRev and will present the data exactly as the file was saved. If the file was saved with an earlier version of QRev and additional features and quality checks have been updated in the current version the following dialog will be displayed giving the user the option of viewing the data as it was saved or reprocessing it. If a change is made to the data the data will be reprocessed using the features of the current version.
