  In symplectic field theory (SFT), the moduli spaces of $J$-holomorphic curves
can be oriented coherently (compatible with gluing). In this note, we correct
the signs involved in the generating function $\mathbf H$ in SFT so that the
master equation $\mathbf H \cdot \mathbf H = 0$ holds assuming transversality.
The orientation convention that we use is consistent with that of
Hutchings-Taubes from [HT09].
