How does Bedtools coverage work?

How does Bedtools coverage work?

The bedtools coverage tool computes both the depth and breadth of coverage of features in file B on the features in file A. For example, bedtools coverage can compute the coverage of sequence alignments (file B) across 1 kilobase (arbitrary) windows (file A) tiling a genome of interest.

How do you calculate average reading depth?

The mean mapped read depth (or mean read depth) is the sum of the mapped read depths at each reference base position, divided by the number of known bases in the reference. The mean read depth metric indicates how many reads, on average, are likely to be aligned at a given reference base position.

How to calculate mapping statistics from a BAM file?

One-line text comment. Unordered multiple @CO lines are allowed. The mean read depth, the breadth of coverage of the reference genome, and the proportion of the reads that mapped to the reference genome can be obtained from a BAM file using the combination of awk, and the SAMtools 1.3.1 utilities depth and flagstat.

How to calculate the mean read depth in Bam?

The mean read depth is s/c. samtools depth -a file.bam: Computes the depth at each position or region. The -a flag indicates that the depth must be calculated at all positions, including at those with zero depth.

How is smooth length calculated in bamcoverage 3.5.0?

The smooth length defines a window, larger than the binSize, to average the number of reads. For example, if the –binSize is set to 20 and the –smoothLength is set to 60, then, for each bin, the average of the bin and its left and right neighbors is considered. Any value smaller than –binSize will be ignored and no smoothing will be applied.

Can a bed file be excluded from a Bam analysis?

A BED or GTF file containing regions that should be excluded from all analyses. Currently this works by rejecting genomic chunks that happen to overlap an entry. Consequently, for BAM files, if a read partially overlaps a blacklisted region or a fragment spans over it, then the read/fragment might still be considered.
