neg.contr


The ``hiv'' section of this dataset consists of cDNA from CD4+ T cell lines at 1 hour after infection with HIV-1BRU. There are 4608 genes' expression levels. There are four replicates with balanced dye sways i.e. two of the replicates have sample 1 labeled with red and sample 2 labeled with green and the other two have the opposite labeling scheme. It is useful in testing the specificity of methods identifying differentially expressed genes, since there are 29 genes known not to be differentially expressed (non-human genes), called negative controls, identified in the vector of logical values ``neg.contr''.

Package for normalizing microarray data in single and multiple
replicate experiments and fitting a normal-uniform mixture to detect
differentially expressed genes in the cases where the two samples are being
compared directly or indirectly (via a common reference sample)
