denovoGenomeExpr-class: Class "denovoGeneExpr"

In casper: Characterization of Alternative Splicing based on Paired-End Reads

Description

denovoGeneExpr stores inferred expression for de novo splicing variants for a single gene. denovoGenomeExpr stores the information for several genes (typically, the whole genome).

Objects from the Class

Objects are returned by calcDenovo. When running calcDenovo on multiple genes results are returned in a denovoGenomeExpr object. Results for a single gene can be retrieved using the [[ operator as usual, which returns a denovoGeneExpr object.

Slots

posprob

data.frame containing the posterior probability of each model

expression

data.frame with the estimated expression of each variant under each model

variants

matrix indicating the exons contained in each variant.

integralSum

Sum of the log(integrated likelihood) + log(model prior probability) across all considered models.

npathDeleted

Number of paths that had 0 probability under all considered variants and had to be excluded for model fitting purposes.

priorq

Input parameter to calcDenovo

txLength

Length of transcripts in bp (including new isoforms found by casper)

Methods

signature(object = "denovoGeneExpr"): Displays general information about the object.

posprob

Accesses the posterior probabilities of each model (slot posprob)

variants

Accesses the variant names and their respective exons

variants<-

Replaces the value of the slot variants (can be useful for renaming variants, for instance)
