Subject: Wave rotation during transfer from the board? 

This is correct. Actually the amplitude array is rotated already inside the DRS4 chip. So the readout starts with the stop cell plus one. If you do not do anything, the waveform is already "rotated". If you want the waveform to start with physical cell #0, you have to "unrotate" it.
