The H_CODE, V_CODE, and NGS_CONTROLS containers contain features only associated with synthesis QC and alignment, and so are not exported in a .pair file unless the "Include controls?" box is checked in the Pair Report dialog in NimbleScan. Since those features are of little or no utility for analysis after an experimental hybridization, they are not included in pair reports by default. Those three containers will be contained on all array designs. The remaining containers (from 1 to N) can be named a variety of different names. BLOCK1 through BLOCKN are typical names for containers containing replicate probes (or sometimes FORWARD/REVERSE), and the RANDOM container contains randomly generated probes with the same length and GC composition as the experimental probes which can be used to estimate non-specific binding. Container naming is often up to the customer and so they can vary a great deal.
