How-to

This is a walk through for setting up and using the application. If you want to review the code or contribute, you can find it on github

Install

First download the Matlab app installer from github: Image Indent_App.mlappinstall

Then open Matlab and select the App tab Image and click on Install App Image head to your download folder and select the Indent_App.mlappinstall file. The application is now included in the list of Matlab Apps and you can open it by clicking the logo. Image

Use

Load measurement data

The first thing you need to do is export the files from Nanosuite. Please export to *.csv: while the application can read excel files, it is much quicker to load *.csv files. Besides you won't depend on a Microsoft Excel license. Make sure each batch has its own folder a *.csv files tend to have the same names for a single batch of tests: Results.csv, Inputs Editable Post Test.csv, Test 001.csv, etc.

Then you need to turn your csv or xls file into a structure that Matlab can read. With the Indent App

Click on file > file 2 struct (alternatively you can select file 2 struct (no test) if you don't need test data) Select your main file: either a .xls file (slow) or Results.csv (fast). In the latter case, the application will take care of loading the data contained in the other files within the same folder. The application creates a structure containing all the data. This structure is loaded into the application and on the Matlab Workspace. It also saves the structure in the same folder into a matlab file (.mat). That way you can simply load the structure into your Matlab workspace next time you need these data.

After loading the data into your application, it should approximatively look like that (depending on your OS): Screenshot of the Indent App after loading a Matlab Structure.

Visualize your data

The data of one or several tests can be plotted by selecting them on the left (hold CTRL to select several tests), selecting the measurements for the X and Y axes and then clicking on PLOT. If you have a grid of data, you can plot a map of their elastic modulus by pressing MAP INDENT. You can interact with this map to select the tests and plot them. The selection in the test list on the left will update accordingly. The Map can be modified:

The elastic modulus is averaged over a certain penetration depth range (it depends on how you configured Nanosuite before exporting). You can change this range by going to edit>Change av. disp.. If you have a micrograph of the indented area, you can superimpose this image (preferably *.png) with the map. Click on edit>calibrate image select your image file select how many times it should rotate it of 90° Select the 2 indents located at the bottom left hand corner and the top right hand corner of the grid. Close the image and click again on Map Indent Select the desired transparency with the Map ... Image slider.
