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.

In the Select Raw Data (.RSA) Files window, click on the Add button.

Select one or more files to export for viewing in SAAView. Once the files have been selected, click the Open button.

If the data being exported is for a ShapeArray installed in convergence or multiple ShapeArrays that overlap to form a Super SAA, then you must also specify a site file for the export process. More information about creating site files for ShapeArrays installed in these configurations is available in the Creating Site Files for Convergence and Superset ShapeArrays article on our Support web site. If necessary, select the Use Site Calibration File checkbox at the bottom of the Select Raw Data (.RSA) Files window and click the Browse button to select a site file.


Once you have selected your raw data (.RSA) files, and a site calibration file if necessary, click the OK button to continue.



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

If there are already converted data in the selected folder, a pop-up window will appear requesting to append or not. 

  • Yes, Append Files - Click to append data to previously exported files that already exist in the data folder 
  • Re-convert Everything - Click to completely overwrite any previously exported data files that might already exist in the data folder 
  • Cancel - Closes the export



Step 3 - Configure ShapeArray Conversion Parameters


In the SAA Conversion Parameters dialog, select the options that suit the ShapeArray raw data files selected and choose a Site File if required. Click the OK button to continue.

  • 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
  • Adjustment: 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 
  • SlavedSegments: A comma separated list of slaved segments
