Hi,

I'm currently doing a study using Affymetrix GeneChip Human Gene 1.0 ST v1.
I have a batch of 8 arrays from the first batch and 20 arrays from the
second batch. When i look at the density plot of the log2 of the intensity
values before preprocessing, there seems to be a bump small bump in the
higher intensity range. I'm under the impression that this means there is
saturation of the chips and I will need to either filter or process the data
before further analysis.

I can't seem to find any information on how to procede in my analysis. Any
experience or insight would be greatly appreciated.

Dennis
