Hello,

We would like to use the model "convgamma" in 3dNLfim with a stimulus file that is not 1 and 0s.
(It actually is the end tidal partial pressure of co2: Pco2).
When we do: setenv AFNI_CONVMODEL_REF pco2.1D , we get an error message about the AFNI_CONVMODEL_REF.

Is it because it is not a 1 and 0 file ? If yes, what would you suugest to do ?

Thank you in advance.

Julien.
