MVPA Data Scaling

Hi all,

I have used the Decoding Toolbox (TDT) for a searchlight MVPA with a 4-fold leave-one-run-out-classification and was wondering about the scaling option. I have set the following parameters:

        cfg.decoding.method = 'classification_kernel';
        cfg.results.output = 'accuracy_minus_chance';

Which I am now realizing has invoked the default settings for scaling:

        cfg.scale.method = 'min0max1global';
        cfg.scale.estimation = 'all';

Is this the correct approach? What would be different if I set the scaling to ‘min0max1’?

Thanks a lot!
