Raw data recorded in SAARecorder as .rsa files can be converted to a multi_saa_allcart.mat file that can be opened in Measurand’s SAAView application. SAAView has many graphical interfaces and options available for viewing ShapeArray (SAA) data over a long period of time.
Step 1 - Select your Files
In SAARecorder, from the File menu, select the Export raw data to SAAView option.

Step 2 - Select Averaging Setting
In the Time vs. Samples dialog, select the appropriate averaging setting and click the OK button.
- File Averages - Data arrives from files, concatenated together. - Performs discrete averages, one per file (Output = 1 sample per file).
- No Averaging - Leave raw data unchanged. Note that SAAView expects at least 2 samples when displaying data, use this option if a single file is being converted for viewing in SAAView.
NOTE: The Step Averages, Discrete Average(s) of, and Running Average of options should only be used with older model ShapeArrays. These options are included for compatibility with legacy products and should not be used with modern ShapeArrays

- Sernum: The Serial Number of the ShapeArray
- Vertical: Is the ShapeArray vertical?
- Ref=Far: Is the reference end the far (tip) end?
- Az. Deg: The azimuth offset of the X-mark on the ShapeArray in degrees
- NumSeg: The number of Segments in this ShapeArray
- Correction: Allows software adjustments to be applied to the converted data
- StartSeg: The segment to start with. This allows for skipping starting segments
- EndSeg: The segment to end with. This allows for skipping end segments
- SlavedSegs: A comma separated list of slaved segments
