The PMTK3 loadData function automatically downloads required data sets from the pmtkData website. To ensure that this works for new data sets, please follow these guidelines:

• Each data set must live in in its own folder and have exactly one .mat file. Store any processing scripts and source data in this folder as well.

• The name of the .mat file and the folder must be the same.

• Each data set must have a foo-meta.m file stored in the pmtkData/meta directory, where "foo" is the name of the data set. This file stores "meta" information used to generate this table.

• Each line of the foo-meta.m file begins with a % followed by a space, and contains a PMTK tag along with its data. Here is an example.

• Check the folder in to svn.

• Zip up the new folder by running the following PMTK command:

refreshZipFiles('data' 'foo');

The refreshZipFiles function automatically excludes .svn directories before creating the zip file, which is stored inside the foo directory. If you are zipping up a folder manually, make sure not to include the svn info, either by doing this before you check the folder in, or by running svn export.

• Check the folder in to svn again, to include the .zip file.

• Test auto-downloding with loadData('foo') making sure the folder you just created is not on your MATLAB path.

• Run generatePmtkDataTable to update the list of datasets.

• That's it
