Actually, there is a study indicates slice timing has minimal effect on resting-state FC, ALFF/fALFF.

For task related data, that might matter. "Depending on repetition time and paradigm design, slice-timing effects can significantly impair fMRI results and slice-timing correction methods can successfully compensate for these effects and therefore increase the robustness of the data analysis."

Re: SLICE TIMING
I personally don't think it is necessary. I am afraid no study has proved. However, almost everybody does so.
