SIE data files
SIE data
The SIE data pane displays all SIE data files stored on the connected device.
- File name: The file name provided from the Test control page before the test run. A red test name indicates that the test is currently running.
- Size (KB): The size of the SIE data file in KB.
- Modified: The date and time that the SIE data file was last modified.
- Author: The test author provided in Test setup.
- Summary: The test summary provided in the Test setup.
- Run description: The Description provided from the Test control page before the test run. If nothing was entered, this column will show the text No Run Description.

Row sort preference persists through GUI refresh, unit reboot and firmware update. Deleting the database or resetting user preferences will reset the sort preference. Formerly, sort preferences defaulted to the File name column.
NOTE
The system is not designed to handle a large number of SXR or SIE files in an optimally user friendly manner. The reasons for this are complex. In brief, the user interface responsiveness will be degraded when too many SXR or SIE files exist. To avoid this situation, a good rule of thumb is to limit the number of SXR files to 20 or less and the number of SIE files to 50 or less. In situations where this is not feasible or desirable, the system will continue to function properly, but not optimally in regard to user interface responsiveness.

The easiest way to download a single SIE file to the local machine is to click its file name. Alternately, select the check box next to the desired file and click Download. Multiple SIE files can be downloaded by selecting multiple check boxes. However, only Chrome supports this well currently and that is subject to change.
See the topic SIE file metadata for information about SIE file content.
The XR Download Manager application is provided to circumvent all browsers and provide reliable and robust downloads of multiple SIE files, and as such, is recommended. This application may be downloaded from the HBM website under Software for QuantumX & SomatXR. See Personal computer support applications for Download Manager installation instructions.
Downloading SIE files (including the active SIE file) is allowed when an SIE data collection test in running. Please note the following.
- Downloading SIE files requires CPU processing that competes with normal test run CPU processing. It is possible that starting an SIE download will result in overloading the system to the point where the test will stop and the system will reset. This is of primary concern when the test is already loading the CPU significantly (for example, 80% or more). However for any test where an error reset is considered unacceptable, users are strongly advised to wait until the test is stopped before downloading the SIE file.
- The CX23-R/EXRCPU buffers test data in memory before it is written to the SIE file. As a result, an active SIE file downloaded while a test is running will not contain acquired data that has been buffered, but not yet written. Some DataModes™, such as histograms, are not completely written to the file until the test run is stopped. Download the file again after the test has stopped to ensure that the file contains all test data.
NOTE
It is good practice to ensure that the complete file has been downloaded. To do this, compare the file size of the downloaded file to the size of the listed SIE file. Mouse over the Size entry in the grid to show the exact file size in bytes.

Select the check box next to the file and click Rename.
The file name must be unique and contain valid characters (invalid characters are single and double quotes, '\', '@', '#', '&', '<' and '>' or the problematic character string ".sie" [case sensitive]). When ';' is in a test setup name, '_' replaces ';' in the SIE file name generated by a test run.
. Enter a new file name and click Save.

Select the check box next to a single file or multiple files and click Delete to remove the file or files from the connected device. Depending on how many files are selected, the process may take several minutes. Deleted files cannot be recovered!

Several types of data and information can be extracted from SIE files including the test setup, hardware information and raw channel data.
Select the check box next to the desired SIE file and click Extract.
Click the desired extraction option.

Enter the desired file name. Click Export to save the file to the local machine.

Enter the desired file name and click Export. A JSON formatted .sxri text file containing hardware information is saved to the local machine.

Select the desired raw message or video channel. Optionally, enter a test start time and duration in seconds for the extracted data. Click Export to save the data file to the local machine.
TIP
Raw data can also be extracted from channel sources in Message logger DataMode™. This allows the use of triggering to control which segments of the data stream are stored.
For raw message channels, the extracted data is exported to a text file named extracted-data.txt.
For video channels, a .jpg image of each frame is named with its time stamp, placed in a folder named for the camera serial number and downloaded in a tarball file named extracted-data.tgz.
NOTE
Extraction of raw CAN/GPS channels from large data sets using the web interface may be unreliable. The SIE file data itself is not affected. These data sets can be retrieved by downloading the SIE file to a PC and using another application such as the XR Download Manager to perform the extraction.

Several types of data and information can be viewed from SIE files, including strip charts and video.
Select the check box next to the desired SIE file and click View.
The application XR Data Viewer opens in your browser.
View channels by clicking on the green Plus icon in the lower right corner of the viewer, then selecting a channel from a drop down list in the header. A green bar to the right of a channel chart shows the view is selected. Close a view by clicking the red X in the right hand corner of the channel chart.
View the value of a point on a chart by moving the mouse pointer on the chart.
Zoom in or out on the charts using the mouse scroll wheel.
To view more of a chart while zoomed in on a chart, use the mouse pointer to slide the bar on the time scale at the bottom of the viewer window.
