The data are in the form of a 424 by 424 array which contains the scores from using the EMAP procedure on yeast strains which are ideally double mutants, each strain with a different pair of genes knocked out. For each row, the gene named in the row label is knocked out in all pairs, and the same holds true for each column.
gi2005 is a 424 by 424 array of real values.
gi2005.metadata is a vector of length 424 which contains
the common names for the genes that were knocked out. The row and
column names of
gi2005 are standard names.
NA values in
gi2005 are interactions that were not scored.
