In mikelove/tximeta: Transcript Quantification Import with Automatic Metadata

Import transcript quantification with metadata

Description

The tximeta package imports abundances (TPM), estimated counts, and effective lengths from Salmon, alevin, piscem or other quantification tools, and will output a SummarizedExperiment object. For Salmon / alevin / piscem quantification data, tximeta will try to identify the correct provenance of the reference transcripts and automatically attach the transcript ranges to the SummarizedExperiment, to facilitate downstream integration with other datasets. The automatic identification of reference transcripts should work out-of-the-box for human or mouse transcriptomes from the sources: GENCODE, Ensembl, or RefSeq.

Details

The main functions are:

• tximeta - with key argument: coldata

• summarizeToGene,SummarizedExperiment-method - summarize quants to gene-level

• retrieveDb - retrieve the transcript database

• addIds - add transcript or gene ID (see gene argument)

All software-related questions should be posted to the Bioconductor Support Site:
