Tutorial Differential Expression for arrays
[Class comparison](Tutorial Expression. Class comparison). The methods implemented here allow you finding genes differentially expressed within a class, between two or more than two classes. You can find the genes that have expression patterns more differentiated among them.
[Correlation](Tutorial Expression. Correlation). Using this module, you can study gene expression related to a continuous variable. For example, if you treat some cells with different doses of a drug and you also measure their gene expression levels, you can find genes which expression increases or decreases with the level of treatment. Study expression among more two or more array classes. The methods implemented here allow you finding genes with similar expression.
[Survival](Tutorial Expression. Survival). Exploring gene expression related to a survival time. You can study for example which genes are more directly related to the death of your cells by analyzing the relationships between the expression of the genes and the survival time of the cells. Study the relationships between the expression of the genes and the survival time of the cells.
