Click to define the filename (and optional header).
Click to define the number of markers and their corresponding labels.
Click .
The first step is to create a new file. You may do this with the New Marker File button or from the menu bar using File > New Marker File.
File Name: Name the file. The creation date will be appended to your filename.
Header (optional): You may also include text that will be included in the output file.
Save: Creates a text file that will save the timestamped marker recording. Files will be saved to the same location as the Markers application.
Cancel: Discards changes made in this window.
Save: Saves your input and returns you to the main window. Notice the Filename text has changed from None to reflect the name of the new marker file.
In the root directory (the same folder location as the application), you should also see your newly created file. It includes the file creation date and time and the header. If you did not define a header, default_header is used.
Set the number and names of markers.
From the main window, hitting the Define Markers button should display a new window. Select the number of markers to define (up to 18).
Then, with the number of markers selected, type the marker labels to use in your recording. Alternatively, you may skip this step and the default labels will be used.
Skip (use defaults): A label will automatically be generated for each marker. (e.g, marker0, marker1, etc.)
Save Markers: The markers will override active markers and you will be returned to the main window.
Cancel: Discards any changes and returns you to the main window.
If everything worked correctly, your newly defined markers should appear near the Active Markers label.
Begin logging markers to the file.
Press a marker button to add it to the marker file.
Repeat until you are ready to finish the recording.
Hit Stop to end the recording and save the Marker File.
Keep window on top: Set this checkbox to selected to keep the Recording window on top of other windows for ease of access.
The marker file will include the updated log of labels and timestamps.
If you followed along and made it this far, congratulations! You learned how to record custom markers to a file.
One thing you might do next is to combine the marker file with the data log files saved by Metrics to enrich data sets.
You may see these warnings if certain items haven't yet been defined.
Define File: If you see this warning message, a new file has not been created and saved. Close the warning to return to the main window. Create a new marker file and hit Save.
Define Markers: Before you can Record, markers must be defined. Hit OK or close the window to return to the main window. Then, define markers as described in the Define Markers section of the documentation.
