       This is mean to compute a model function for Conv_PRF_DN, given
       NT and a set of parameter inputs.
    
       consider something like:
    
           setenv AFNI_CONVMODEL_REF conv.ref.GAM.1D
           setenv AFNI_MODEL_PRF_STIM_DSET stim.144.LIA.bmask.resam+orig
           setenv AFNI_MODEL_PRF_ON_GRID NO
    
           setenv AFNI_MODEL_PRF_GAUSS_FILE gauss_dset
    
           # params: A0 X Y Sig0 B0  A1 Sig1 B1
           set nt = `3dinfo -nt $AFNI_MODEL_PRF_STIM_DSET`
           get_afni_model_PRF_DN $nt 5.9 -0.6 0.1  0.3 4.9  2.3 0.5 -1.4
