Two-tailed and one tailed tests generally give different p-values, with the
two-tailed p-value twice (one of) the one-tailed values for rather obvious
reasons. You need to sort out which question you wanted the answer to.
Having said that, if a factor of two in the p-value changes your
interpretation, you probably haven't got a really compelling result.
