			Note that a data block is saved together with the state vector that existed immediately after it was acquired.
			Thus, ''PreStimulusTime'' will be the prestimulus time of the block prior to the current block.

	<code>PresentationID = SourceTime << 8 \| (RequestTime - SourceTime) & 0xff</code>		<code>PresentationID = SourceTime << 8 \| (RequestTime - SourceTime) & 0xff</code>

			This definition makes presentation ids unique within the range of a minute, and allows to extract the value of the request's time stamp from its id.
