Hi All,

I am using the Spellman dataset available through the 'yeastCC' package. The documentation says that the data is derived from the Spellman data available at:

http://genome-www.stanford.edu/cellcycle/data/rawdata/combined.txt

I wanted to know what processing was done to the data to yield the data in the yeastCC package. For example:

On Spellman website:
--------------------------------------------------------------------------------------------------------------
            cln3-1    cln3-2    clb2-2    clb2-1 ...
YAL001C    0.15    NA         -0.22         0.07   ... 
--------------------------------------------------------------------------------------------------------------


In yeastCC dataset:
--------------------------------------------------------------------------------------------------------------

            cln3.1    cln3.2     clb2.2     clb2.1  ... 
 YAL001C  0.4974186  0.000000 -0.7262840  0.2328342 ...
--------------------------------------------------------------------------------------------------------------


I read the 'createYeastCC.r' file as suggested in the documentation, but couldn't make out what processing/normalization was done to the data, and why it is different from the combined.txt that is available on the Spellman website.

I do apologize if my question is very basic. 

many thanks!
