  We consider an attractive quasi-one dimensional spin-orbit coupled
Bose-Einstein condensate (SOC BEC) confined in a periodic potential produced by
the combination of linear and nonlinear optical lattices, and study the effects
of squeezing a stripe soliton by varying the inter-atomic interaction in the
nonlinear lattice. It is observed that the nodes on the soliton arising
entirely due to the effect of spin-orbit coupling tend to disappear as we
increase the squeezing effect to finally get a stable fundamental soliton. This
leads us to conclude that external pressure can reduce the effect of spin-orbit
coupling in the SOC BEC and even convert the system to a traditional BEC
without spin-orbit coupling. We make use of an information theoretic measure to
visualize how does the atomic density distribution in the condensate respond to
continual reduction in the spin-orbit coupling effect.
