Compute the Divergence Stratum Contribution to the Global Transcriptome Divergence Index
Description
This function takes a standard ExpressionSet object and computes the partial contribution of the different divergence strata (ds) to the global Transcriptome Divergence Index profile.
Usage
pTDI(ExpressionSet)
Arguments
ExpressionSet |
a standard DivergenceExpressionSet object. |
Details
This function (pTDI) computes the partial TDI contribution for each phylostratum and each developmental stage and returns a data matrix storing the partial TDI contribution value for each divergence and each developmental stage.
