Subread package: high-performance read alignment, quantification and mutation discovery
The Subread package comprises a suite of software programs for processing next-gen sequencing read data including:
- Subread: an accurate and efficient aligner for mapping both genomic DNA-seq reads and RNA-seq reads (for the purpose of expression analysis).
- Subjunc: an RNA-seq aligner suitable for all purposes of RNA-seq analyses.
- featureCounts: a highly efficient and accurate read summarization program.
- exactSNP: a SNP caller that discovers SNPs by testing signals against local background noises.
These programs were also implemented in Bioconductor R package Rsubread.
Release 1.5.0-p3, 27 May 2016
Fixed a bug associated with '--allJunctions' option in Subjunc aligner.
Improved the efficiency of exactSNP program when calling SNPs from the data that have a very high sequencing depth (>1000x).
Resoved an issue of concurrently opening a large number of files in featureCounts.
Improved processing of 'H' operations in CIGAR strings in featureCounts.
Release 1.5.0-p2, 14 Apr 2016
subread-align and subjunc
- Fix a bug in processing long header lines in SAM/BAM files.
- Depreciated the '-S < ff:fr:rf >' option.
- The '< input file >.featureCounts' files (generated when '-R' is specified) are saved to the same directory as the file < output_file >.
- Fixed a bug related to reporting of reads mapping out of the chromosomal boundary.
- Make sure no zero operations (eg '0M') are included in reported CIGAR strings.
- Fixed a bug in soft-clipping read bases.
- Improved screen output.
Release 1.5.0-p1, 18 Dec 2015
featureCounts can process long reads (up to 250kb long). It can also process reads that contain long extra fields.
Report counts for exon-exon junctions by featureCounts ('-J' option).
Improved parsing of gzipped fastq files in Subread and Subjunc aligners.
Release 1.5.0, 29 Oct 2015
subread-align and subjunc
- Improved speed of re-sorting paired-end reads. It now takes only about 30 seconds to re-sort 30 million read pairs.
- A utility program `repair' to provided to allow pre-sorting of pair-end BAM/SAM files.
- New parameter '--type' for sequencing-type-specific mapping optimization.
- New parameter '--sv' for detection of structural variant breakpoints.
- New parameter '--complexIndels' for detection of complex indels.
- Improved mapping of paired-end reads via a new formula that uses weighted votes (more weight is given to properly mapped reads).
- Improved detection of multi-mapping reads by considering locations that receive second highest votes.
- When gzipped fastq input is provided, reads will be directly extracted from the gzip-compressed file and no temporary files will be generated.
- Default output format is set to BAM.
- Default threshold for removing un-informative subreads from index is changed to 100 to allow more candidate mapping locations to be considered.
