Description:

Purpose

This App can be used to filter surface profile with a gaussian filter and calculate roughness parameters.

Installation

Download the roughParam.opx file, then drag-and-drop onto the Origin workspace. An icon will appear in the Apps gallery window.

Operation

  1. Activate a worksheet and highlight XY columns which contains xz coordinates.
  2. Select Gaussian Filter Type:
    • Short Wavelength Pass: The filtered profile is roughness profile (< cutoff length).
    • Long Wavelength Pass: The filtered profile is waviness profile (> cutoff length).

    Notes: A few number of starting and ending points of the profile data will be truncated after gaussian filter is applied.

  3. Enter value in Cutoff Length (the unit of cutoff length is the same as that of z profile).
  4. Select quantities to calculate.
  5. Click Preview button to display filtered profile.
  6. Click OK to output results.

Sample OPJU File
This app provides a sample OPJU file.  Right click the App icon in the Apps Gallery window, and choose Show Samples Folder from the short-cut menu. A folder will open. Drag-and-drop the project file Surface Roughness Parameters Sample.opju from the folder onto Origin. The Notes window in the project shows detailed steps.
Note: If you wish to save the OPJU after changing, it is recommended that you save to a different folder location (e.g. User Files Folder).
