4-Sample Alignment #15
Description
Currently it is up to the user to align on a 4 sample boundary or pay the penalty when APSPattern.py rounds the count down to the nearest 4 sample boundary. Most of the time this just gives some inter-sequence jitter. However in a longer sequence with a repeated block, e.g. a CPMG sequence, if the pulse spacing is not aligned then the truncations accumulate leading to sequence timing that is much further off.
It should be possible to more elegantly handle this and to never be more than 4 samples away from the desired sequence.
