Description

This X-Function is used for importing NI TDM data files generated by NI DIAdem Version 10.0. It allows you to import the structure of a file, and then separately re-import selected data using the reimport X-Function.

Examples

  1. In this example, we will import NI TDM data :

    2. a. From the Origin menu, select Data: Import from File: NI TDM (TDM, TDMS). This opens the TDMFiles dialog, allowing you to choose the import file.

    b. Browse to the folder containing your data file is. Select the file and click the Add File(s) button. Click OK to close the dialog box.

    c. In the impNITDM dialog box, Select the groups and channels you want by selecting the check-boxes to the right of them. Click OK to close the dialog.

  2. The following script command imports an NI TDM file (c:\test.tdm) without opening the dialog:
    3. Fname$="c:\test.tdm";
impNITDM;
