Faq make DataSet backwards compatible

How do I make a DataSet backwards compatible?

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:

Try using the struct2dataset function to generate a DataSet from the structure:
```
>> newdso = struct2dataset(oldstruct);
```
If you only need the data, extract the data from the structure into a new dataset:
```
>> newdso = dataset(oldstruct.data);
```
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.
