The controls in the upper side of the dialog provide basic information about the file being imported: its location (displayed in the Path label) and its size (displayed in the corresponding Size label).
The dialog also displays the structure of the TDMS file in a tree widget allowing the selection of the groups and channels to be imported. It is possible to enable/disable the import of an entire group or of individual channels by checking/unchecking the corresponding box situated on the right side of the selection tree. A double-click on the name of a channel opens an information message box displaing the number of data values in this channel toghether with the list of its properties.
If the Preview box is checked QtiPlot displays a plot of the raw data values stored in a channel when you hover the mouse pointer over the channel name. The preview image is not available for channels with strings, time stamps or complex data types.
QtiPlot creates a new table for each group imported from the TDMS file. By checking the New Folder box these tables are moved into a subfolder inside the current folder of your project. The name of the new subfolder is generated automatically based on the name of the TDMS file.
