Hi,

I am reading the documentation on 3dDeconvolve and I'm trying to find the equation that involves the scaling factor between the regressor functions (e.g. stimulus files, usually normalized to 1) and the amplitude of the data.

Can you please tell me how 3dDeconvolve finds the beta weights without caring about the amplitude difference between the regressors and the data?

thank you!
