Faq make DataSet backwards compatible

Issue:

How do I make a DataSet backwards compatible?

Possible Solutions:

I received the following error when I loaded a dataset into Matlab: Warning: Loaded dataset object newer than present constructor. Dataset object converted to structure.

This happened because the DataSet being loaded is of a new version than the current DataSet Object. There are a couple of ways to get around this:

1) Try using the 'struct2dataset' function to generate a DataSet from the structure:

>> newdso = struct2dataset(oldstruct);

2) If you only need the data, extract the data from the structure into a new dataset:

>> newdso = dataset(oldstruct.data);

3) Obtain the latest DataSet Object (the "@dataset" folder), either separately from our website or as a part of the latest version of PLS_Toolbox. Note that this might not solve the problem if your DataSet was created with a Beta (unreleased) version of the DSO.
