In fact, you can use any sort of files as you like, just load your data into MATLAB and create a data object. All methods work with data objects. However, if you want to use the leading functions which comes in sample code section, try to download one of the challenge files and see it’s format, e.g. http://www.modelselect.inf.ethz.ch/datasets.php

I tried to use your package however I wonder what is the data file format. I could not find in any documents that how the files and file formats should be. I am actually try to use your package for feature selection. I almost check all feature dataset fie format but non of them works. I got the following error and so far I couldn\’t find what is the reason.

??? Error using ==> fscanf
Invalid file identifier. Use fopen to generate a valid file identifier.

Error in ==> read_parameters at 12
p.data_type=fscanf(fp, \’Data type: %s\\n\’);

Error in ==> create_data_struct at 19
p = read_parameters(filename);

Your toolbox CLOP is really a great works. Thanks very much for this excellent package.
