Assessing Quality of Error Correction
The main idea:
Given fastq/fasta files containing reads(simulated from ref. genome, with errors introduced) and another file with the ground truth(simulated but without errors) and then the resulting ...

If fastp output is not a good measure of FASTQ correctness, what is?
In the beginning of my pipeline, I just fed the paired reads (2 files) into fastp, with the default options, and assumed it would do a good job preparing the reads for the next step: alignment
But I ...

Total read count of shotgun affected by few highly abundant sequences
I am building statistical models to analyse output from Illumina shotgun sequencing (HiSeq 4000) on stool samples (but RNA-seq data should behave similarily). The raw counts are a statistical sample ...

At what stage of a transcriptome assembly is it better to perform read contaminant filter?
I'm trying to assemble a bivalve transcriptome. Since bivalves are filter feeders, their transcriptomes tend to be highly contaminated by bacteria, algae and whatnot. Since I pooled several ...

How to force pilon to correct a reference with low coverage mapped reads?
I have mapped some reads to a reference and want to change SNPs in the reference to SNPs found in the reads, even at low coverage. For example, here is a screenshot of one reference in IGV that I ...

Can I pilon-polish long reads with Illumina short reads to improve structural variant detection?
I have pacbio Sequel data at 50 x coverage for a strain of animal. I would like to find structural variants compared to the reference genome sequence. At the moment, I align my reads to the reference ...
