Numbers of beads

Quantity of starting RNA:	250 ng	100 ng	50 ng	10 ng
Total decoded	18,801,235	17,835,076	17,926,750	19,274,434
Removed by BASH	200,459	408,721	284,088	50,449
Removed in summarization	651,323	614,495	603,619	582,345
Remaining	17,949,453	16,811,860	17,039,043	18,641,640
In analysis-group bead-types	7,963,638	7,475,940	7,563,440	8,248,259

Summing across all array-sections in the four experiments, we list the total numbers of beads (as decoded by Illumina), the numbers we remove as being in spatial artefacts using BASH [19], those removed as being outliers in the summarization, the remainders, and the numbers remaining that lie in the analysis-group of bead-types.
