I’ve heard oligo arrays have higher noise compared with BAC arrays?
All our data presented is raw and unsmoothed. However, our data has been normalised. In general, BAC array data is the result of averaging multiple spots. Our oligo arrays are designed with 1,000s of probes in the target sites, so although the data might appear to be noisier, there is greater certainty in the outcome of data analysis since there are many more data points.
