Slopes = ( atan ( (dzdx^ 2+dzdy^ 2 )^ 0.5 ) / ( 2 * pi ) ) * 360 //slopes in degrees are between the normal of the facet and the nominal sample normal This article discusses the different approaches to software customisation and describes the use of two sets of macros in the analysis and processing of AFM images. SetScale / P x 0, (mini_wave_scaling ), "", mini_y SetScale / P x 0, (mini_wave_scaling ), "", mini_x They will cause errors the first time the function is used. RemoveFromTable slopes, mini_x, mini_y //probably could comment out all of the remove/kill statements, but they can be useful. Prompt mini_wave_scaling, "Enter nm/point value: " // Set prompt for x-y scaling (example: this should be ~9.78 nm/point for a 512 x 512 pixel image that is 5 microns on a side) Variable X_index, Y_index, totalcycles= 0, array_size, mini_wave_scaling= 1 Assumes that the AFM image has been plane filtered, is loaded into a 2D wave, and has heights in nanometers Similar to the output of Gwyddion image analysis software after selecting Data Process->Statistics ->Slope Distribution -> Inclination (theta) in Surface and Interface Analysis 25 (1997) 741. Calculates a histogram of slopes of facets in AFM images.
