Hello everyone,

I use spm for analyse and preprocessing some fMRI resting-state data and i would like to define the GLM , i want to use a discrete cosine basis as principal regressor with frequency range 0.0078-0.1.
how can i define this regressor with this frequency rang?
how can i give DCT frequency range?

Thank you
sr.shn

Sorry that I am not clear with what is GLM and DCT, and maybe I am unfamilar with these, sorry
