Data Acquisition Toolbox

Saving and Loading the Session

During a data acquisition session, you may want to save your work to one or more disk files in order to document or debug your application, post-process data, and so on. The components of a data acquisition session that you can save to disk are divided into two separate parts:

• Device objects and their associated property values
• Information associated with acquiring data with an analog input object including:
• Acquired data
• Event information
• Device object and channel information
• Hardware information

You can save specific components of your session to an M-file using the obj2mfile function, to a MAT-file using the save command, or to a binary ''.daq'' file using the LoggingMode property.
