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
show
signature(object = "denovoGeneExpr"): Displays
general information about the object.
names
Show names (island ids)
"["
Selects a subset of genes
"[["
Selects a single gene
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)
