![]() ![]() This package is similar to WaveMetrics', from which it borrows liberally. To customize the NaNing operation, hold down the key while releasing the menu item ( CAUTION: do not release the key until the dialog appears, or the default behavior will occur) this functionality requires that the GetInputState XOP (or an alias to it) be placed in :Igor Extensions. All data points from all traces within the marquee will be set to NaN, after ensuring that the original trace is backed up. Click within the marquee and select the popup menu item JEG_NaNMarqueeData. To use, select a set of points in a graph with the marquee tool. This is useful for excluding noise and other extraneous data from fits or plots (I take no responsibility for the future of your immortal soul if you use these routines excessively). Uses marquee to set selected points in graph to NaN. ![]() JEG NanoLoader This package for loading Digital Instruments NanoScope ® data files has its own page. How can a difference be relative to anything? Needs: For instance, it should be trivial to add NanoScope®'s R max if anybody can explain to me what on earth “This is the difference in height between the highest and lowest points on the surface relative to the Mean Plane” means. I'd be happy to add other statistical measures, if requested. Note: If the data dimension units are changed after the statistics panel is displayed, the change will not be reflected in the panel. Igor has no way of knowing that most humans don't use picometers. Moreover, if the wave is of integer type, these routines will attempt to apply the integer scaling described in JEG Color Legend.īecause Igor's string formatting routines rigorously apply SI prefixes (I guess, now that I work for NIST, I should praise them for this), rather than "1.000 Å" or "0.100 nm", the panel will display "100.0 pm". The statistical values are displayed with the data dimension units of the image wave, if available. If the Marquee lies outside the image, the statistics calculated will be for the nearest edge. Removing the Marquee does not trigger an update (I have no control over this), but you can click the "Full Image" button, in this event. If a Marquee is drawn out in the image, the statistics panel will be automatically updated to reflect the values for the region within the marquee. A panel is then displayed which shows several commonly cited (and virtually meaningless) statistics for surface morphologies, such as calculated by the NanoScope™ software. Selection of this item, allows the user to select an image from the topmost graph. ![]() These routines add a "Roughness…" item to the Analysis menu. Window hooks must return 0 unless they do something. #include " JEG Window Hooks" History: modified.dB scaling and Hann windowing can be applied dynamically, as can the display of the phase wave. The FFT is calculated from the portion of the trace between the cursors. More extensive documentation is available in HTML format.Ĭreates an automatically updating FFT magnitude (and phase) display of a given trace. Properly determines bounds of complex waves. Supports traces which are displayed with a color as f(z) of another wave. No longer assumes the image is displayed left vs. Preferences panel allows user customization of layout. Specifically, if the wave is of integral type, then the data dimension max and min are taken to correspond to the full range of the appropriate integer size, e.g., an 8 bit unsigned integer wave with data dimension full scale of 0-16 nm would scale each data unit to 0.0625 nm and a value of 256 would correspond to 16 nm.Īs of version 3.0, allows offsetting upper or lower threshold to zero. This package, a subset of JEG Tools, is a collection of tools for image and graph manipulations, consisting ofĪppends a scale bar for the data dimension of image waves.Ĝontrols at the top of the graph allow live adjustment of data range and color tableĪs of version 2.0, uses a particular interpretation of data dimension scaling. These packages are components of my JEG Tools, which you can download for Mac OS or Windoze. ![]()
