Getting started

First of all, download the source code of the Matlab toolbox.

Source code is hosted at Github.

How to use the GUI

First of all a GUI is a Graphical User Interface.

  • Run the following Matlab script :
demo.m
  • Answer ‘y’ or ‘yes’ (or press ‘Enter’) to add path to the Matlab search paths, using this script:
path_management.m
  • The following window opens:

Main GUI for the indentation mapping

The following window opens for indentation mapping:

    1. Initial settings and indentation data loading:
    • Set your type of equipment and units for length and mechanical property. Set ‘Agilent’ in case of .xls file generated using the TriDiMap GUI.
    • Set the number of indents along the X and the Y directions.
    • Import your (nano)indentation results, by clicking on the button ‘Select file’. Click here to have more details about valid format of data.
    • Distance between indents (along X and Y axis) should be automatically calculated, but it is sometimes wrong. In this case, the user has to set carefully (i.e. checking the length unit, it is in micron by default) by himself these 2 distances.
    1. Plot settings:
    1. Average, minimum and maximum values are calculated.
    1. Plot options:
    • Set the colormap
    • Set the colorbar (number of steps, log scale, normalization…)
    • Add markers, min/max values…
    1. Get values from the map by clicking on a pixel.
    1. Buttons to save data (screenshots, .xls file…), to open the 2nd GUI (maps correlation) or to quit…

Check the different file format possible to import in the TriDiMap toolbox: File formats

Note

X-Y axis is given on the top right of the GUI as a reference, to indicate the user how maps are read and plotted…

Warning

Only square or rectangular indentation grids can be loaded into the Matlab toolbox.

Second GUI for the maps correlation (ICBTI)

A second window opens for maps correlation, when user click on the ‘BINARIZATION’:

It is always possible to go back to the main GUI, by clicking on the ‘MAPPING’ button.

    1. Initial settings and indentation data loading (mechanical maps):
    • Set your type of equipment and units for length and mechanical property. Set ‘Agilent’ in case of .xls file generated using the TriDiMap GUI.
    • Set the number of indents along the X and the Y directions.
    • Import your (nano)indentation results, by clicking on the button ‘Select file’. Click here to have more details about valid format of data.
    • Distance between indents (along X and Y axis) should be automatically calculated, but it is sometimes wrong. In this case, the user has to set carefully (i.e. checking the length unit, it is in micron by default) by himself these 2 distances.
    1. Threshold definition to separate soft phase from hard/stiff phase.
    1. Microstructural map loading.
    1. Maps options (colormap…).
    1. Statistical calculations for each map (mean values, phases ratio…).
    1. Buttons to save data (screenshots, .xls file…), to open the 1st GUI (indentation mapping) or to quit…
