It looks like an installation problem. MSDanalyzer is shipped as a class, so you need to install it as a class. Check that the folder containing @msdanalyzer is in the path, but not the @msdanalyzer folder itself.
Tell me if it works.
First I need to say it is a very useful program, thank you for your sharing. However, following the tutorial, the first step is error, when I input mc=msdanalyzer(2,'μm','s'); the matlab will say there is no function for 'private'. Did you find this situation? can you help me for this?
Thank you so much for your help.
