How to Create a Measurement Item in Volocity

A Measurement Item allows you to save and analyze measurements performed on points, lines, or regions of interest in your image data. Follow these steps to create and store a Measurement Item in Volocity.

Steps to Create a Measurement Item:

1. Make Measurements:

   • In the Measurements View, perform measurements on points, lines, and/or regions of interest.
   • Use the analysis tools available in the protocol to track objects or calculate properties of interest, such as volume, intensity, or shape.
   • Example: For a time-series dataset, you can construct a protocol to track objects over time.

   Note:

   • You do not need to include the Measure Objects task in your protocol to create a Measurement Item.
   • Include the Measure Objects task only if you want to measure objects at specific points within the protocol.

2. Use the "Make Measurement Item" Command:
   • Go to the Measurements Menu and select Make Measurement Item.
   • The Make Measurement Item Dialog will appear, allowing you to save your results as a new Measurement Item or append them to an existing one.

3. Configure Timepoint Options:
   • In the Make Measurement Item Dialog, choose which timepoints to measure:
     • Current Timepoint: Measure only the currently selected timepoint in the timeline.
     • All Timepoints: Analyze all timepoints in the time-series dataset.
     • Selected Timepoint(s): Measure specific timepoints that you have selected in the image sequence timeline or the time navigation bar.
   • If no timepoints are selected, the current timepoint is measured by default.

4. Save the Measurement Item:
   • Once created, the Measurement Item will be stored in the Volocity Library.
   • It will appear as a new library entry, allowing you to access, analyze, or export the data as needed.

By following these steps, you can efficiently create and manage Measurement Items in Volocity, ensuring your data is accurately recorded and ready for analysis.
