For example, the
mcf7_hind.cnt
data set (representing quantitative data on relative
SNP
genotypes
found within a breast cancer
cell
line as compared to a normal
DNA
reference sample) was converted from a
.DTT
file downloaded from the
Affymetrix website
to the
.cnt
format using the Affymetrix CNAT software. For more information, please refer to the Affymetrix website (
http://www.affymetrix.com/estore
). The resulting data consist of SPA copy number and
p-values
, which represent individual SNP differences in copy numbers and a corresponding smoothed estimate of copy number (GSA copy number), and associated
p
-value. In addition, a
loss of heterozygosity
(LOH) score and a ratio value of the test
tissue
versus the reference tissue are also included in the CNAT output.
JMP Genomics requires data to be saved as a SAS data set (
.sas7bdat
file). The
Import Individual Text, CSV, or Excel Files
process was used to convert the data set to a SAS data set as described by Robinson
et al
. (2006). The converted
mcf7_hind.sas7bdat
data set, partially shown below, was saved in the
ProcessResults
folder.
