If you want to create a subset of data from the current NDA file, you can use the data filter function. Click the filter symbol on the tool bar to set extraction criteria. You are able to choose different ranges by choosing a filtering pattern, and you can set it to extract all of the data record or partial records from the main channel or auxiliary channel only.
Data Filter Settings
Set the subset data file information including path and file name then click OK to create a subset with the criteria set above.
1) The subset data contains the same channel information as its parent file.
