The reconstruction of a warm inflationary universe model from the scalar spectral index 
and the tensor to scalar ratio r(N) as a function of the number of e-folds N is studied. Under a general formalism we find the effective potential and the dissipative coefficient in terms of the cosmological parameters 
and r considering the weak and strong dissipative stages under the slow roll approximation. As a specific example, we study the attractors for the index given by 
and for the ratio 
, in order to reconstruct the model of warm inflation. Here, expressions for the effective potential 
and the dissipation coefficient 
are obtained.
