Hi Rick,

Thank you for your reply.

That is the message I am seeing:

*** model_conv_PRF: need ref file as AFNI_CONVMODEL_REF

After those commands:

setenv AFNI_CONVMODEL_REF pco2.1D

3dNLfim -input CVRscdtr+orig -TR 2.4 -signal ConvGamma -noise Constant -nrand 1000 -nbest 10 \
-bucket 4 CVRconvgamma \
-brick 0 scoef 0 t0 \
-brick 1 scoef 1 cvr \
-brick 2 scoef 2 k1 \
-brick 3 scoef 3 k2 \
-snfit CVRexpfit12

Thank you.
