Description Usage Arguments Value Author(s) References See Also Examples

To each position of the ordering, this method assigns a value equal to the average of the expression values inside a window, region of n (radius * 2 + 1) proteins centered at a protein. The window considers periodic boundary conditions to deal with proteins near the ends of the ordering.

transcriptogramStep2(object, nCores = 1L)

## S4 method for signature 'Transcriptogram'
transcriptogramStep2(object, nCores = 1L)

`object`	An object of class Transcriptogram.
`nCores`	An integer number, referring to the number of processing cores to be used; or a logical value, TRUE indicating that all processing cores should be used, and FALSE indicating the use of just one processing core. The default value of this argument is 1.

This method creates a data.frame to feed the transcriptogramS2 slot of an object of class Transcriptogram. Each row of the data.frame contains: the ENSEMBL Peptide ID used as center of the window, its position on the ordering, and the mean of the expression values of the window.
