Date: Jan 16, 2008
Submitter: Anonymous
Chip Type: Rhesus
Fitting Function: fitPLM with default background and normalization (using affyPLM version 1.14.0)
Comments From the Submitter: The suspected mechanism causing this effect is related to a chip manufacturing problem.
Comments From the Maintainer: Note that the effect shows up on all the sign images (this is mostly caused by small sample sizes). The images which also include the magnitude of the effect (weights images, residuals images, positive and negative residual images) correctly identify the two arrays showing the effect.
