Description

Sanitize tximport identifiers

Usage

sanitizeTximportIdentifiers(txi)

Arguments

txi	list. tximport list.

Fix transcript identifiers that contain "|" delimters. This can occur when importing GENCODE-aligned data from kallisto, and BAM files from salmon.

No modification occurs for objects not containing these types of identifier.

Value

list. tximport list with corrected transcript identifiers.

Note

Updated 2023-07-25.

Examples

suppressPackageStartupMessages({
    library(tximport)
    library(tximportData)
})
dir <- system.file("extdata", package = "tximportData")
samples <- read.table(file.path(dir, "samples.txt"), header = TRUE)
files <- file.path(dir, "salmon", samples[["run"]], "quant.sf.gz")
names(files) <- paste0("sample", seq(from = 1L, to = length(files)))
txi <- tximport(files, type = "salmon", txIn = TRUE, txOut = TRUE)
txi <- sanitizeTximportIdentifiers(txi)
print(head(rownames(txi[["counts"]])))
