What is bigwig file?

Asked by: Vada Ratke Score: 4.7/5 (25 votes) BigWig is a file format for display of dense, continuous data in a genome browser track, created by conversion from Wiggle (WIG) format. BigWig format is described at the UCSC Genome Bioinformatics web site, and the Broad Institute file format guide provides…

ATAC-seq sample normalization

What you describe seems to be a difference in signal-to-noise ratio which is not uncommon. This is where more elaborate normalization methods such as TMM from edgeR or RLE from DESeq2 come into play. See the following links on why these methods are superior. The videos talk about RNA-seq but…

New biostar-tools metaport for FreeBSD

FYI, FreeBSD users can now install all the bioinformatics software referenced by the Biostar Handbook via FreeBSD ports. Everything except bedGraphToBigWig can be installed simply by running pkg install biostar-tools bedGraphToBigWig is part of ucsc-userapps, which cannot be redistributed for licensing reasons, so there is no binary package. However, the…

Count strand-specific 5′ / 3′ coverage across whole genome for paired-end fragments

I’d like to use bedtools to create strand-specific per-base coverage profiles for my paired-end bam alignments of stranded RNA-seq data. Existing Biostars answers here and here suggest using bedtools genomecov with the -5 option to extract only coverage from the 5′ ends of fragments. These are the commands that I’ve…

Create combined CpG and non-CpG bedgraphs for DNA methylation using Bismark

Create combined CpG and non-CpG bedgraphs for DNA methylation using Bismark 0 Hello, previously, I was using Bismark with the ‘–comprehensive’ option to generate the individual bedgraph files from which we made the bigWigs. For one particular figure, my boss wants me to generate merged bdg files so that we…

difference between treat_pileup and bdgcmp fold enrichment tracks macs2

difference between treat_pileup and bdgcmp fold enrichment tracks macs2 0 Hello, I created bigwig file from a treat_pileup.bdg file generated by macs2 and also used treat_pileup.bdg and control_lambda.bdg with macs2 bdgcmp. Here is my codes; macs2 callpeak -t sample.bam -c sample_input.bam -g hs -f BAM -q 0.001 –bdg –outdir /folder…

Visulization of raw 4C-seq reads in UCSC

Visulization of raw 4C-seq reads in UCSC 1 I’m trying to create bedGraph files to view raw and normalised reads from a 4C-seq experiment to view in UCSC for two biological replicates. Is there a simple way to do this? I’ve tried using bamCoverage and expected to get peaks for…

Merge regions in bedgraph file

Merge regions in bedgraph file 1 I have a bedgraph file with the chromosome, start and end point, and the coverage: CM000994.3 10167710 10167711 95 CM000994.3 10167718 10167720 95 I want to merge regions that are close together. With a bed file I could use something like this: bedtools merge…

Merge regions in bedtools genomecov/bedgraph file

Merge regions in bedtools genomecov/bedgraph file 0 I want to calculate the number of reads mapping to regions of the genome, and I want to group these reads into bins of say 1kb. I have used bedtools genomecov to generate a bedgraph file that shows the coverage of reads across…

STAR split reads into two strands

STAR split reads into two strands 0 Hi all, I’m trying to find a way to split reads mapped with STAR into two separate bam-files, one for each strand. STAR is able to do that when creating bedgraph or bigwig outputs (–outWigType and –outWigStrand), however I can not find any…

bedGraphToBigWig Tutorial and Report

It is too easy to make error report in the bedGraphToBigWig process. I want to save the time for the fresh people. The following procedure would be work well for majority situations.  1, bedGraph should be without header before sorting awk ‘NR!=1’ input.bedGraph > input.deheader.bedGraph 2, bedGraph should be sorted sort…
