Alignment Data

Wild isolate genomes are aligned and stored using the BAM format. BAMs are available in the table below.

Downloading All Alignment Data

You can download all alignment data using the script below. Before this script will work, you need to download and install wget. We recommend using Homebrew for this installation (Unix/Mac OS), or Cygwin on windows. See the FAQ for details on installing wget.

Methods

Information regarding alignment, variant calling, and annotation are available here.

Variant Data

We used samtools to identify single-nucleotide variant (SNV) sites as compared to the N2 reference genome. Variant data are provided as VCF or tab-delimited files.

Learn more about VCF files

VCF

VCFs generated from the variant calling pipeline are provided below.

  • Soft-filtered - Includes all variants and annotations. The QC status of variants is included.
  • Hard-filtered - Variants and genotypes that fail QC are removed.
  • Imputed - An imputed dataset generated from the hard-filtered VCF.

You can programmatically access specific regions of VCF files (rather then the entire file) from the command line:


Strain Data
Strain Data including isolation location, isotype information, and more is available for download.

Included Variants

Currently, we have performed variant calling across all wild isolates. We are working to add additional variant classes including insertion/deletion, structural, transposon, and additional variant classes.

Transposon Data

We have recently performed an anaysis characterizing Transposon variation in C. elegans. The dataset will be further integrated with the site resources as time goes on. For now, the raw data are available below.
