These are the results data from the White
data as measured by the
UT digital PCR on Fluidigm 12.765 digital Array. The data were digtilized
from a supplementary figure "1471-2164-10-116-S1.pdf"
by White et al. (2009) BMC Genomics
A dataframe with 9180 rows and 10 columns.
Position of an array in the figure 1471-2164-10-116-S1.pdf from White et al. (2009) BMC Genomics (e.g., 11 is the image in the first colum and the first row, 24 is second column and fourth image)
is the sample (e.g., "Ace 1:100") as described by White et al. (2009) BMC Genomics
Running index for *all* samples

is the area that was measured with "MicroArray Profile"
is the minimum intensity of an area that was measured with "MicroArray Profile"
is the maximum intensity of an area that was measured with "MicroArray Profile"
is the mean intensity of an area that was measured with "MicroArray Profile"
Setup: Experimental details were described be White et al. (2009) BMC Genomics. The digitalization of the figure was done with imageJ and the "MicroArray Profile" plugin by Bob Dougherty (rpd@optinav.com) and Wayne Rasband.
Annotation: See the White et al. (2009) BMC Genomics paper for details.
