Dear Dr. Alfonso,

I think there may be another bug in the pre-processing pipeline. When performing slice timing correction and selecting BIDS to pick up slicing order (actually timing), the reference slice is specified as half the last slice time i.e. say the last slice was acquired at 2250ms, then the reference slice is specified as 1125ms. I am assuming that instead of this, the timing for the middle slice is what needs to be picked up.
