Data Management – Illumina NovaSeq Geoduck Genome Sequencing

As part of the Illumina collaborative geoduck genome sequencing project, their end goal has always been to sequence the genome in a single run.

They’ve finally attempted this by running 10x Genomics, Hi-C, Nextera, and TruSeq libraries in a single run of the NovaSeq.

I downloaded the data using the BaseSpace downloader using Chrome on a Windows 7 computer (this is not available on Ubuntu and the command line tools that are available from Illumina are too confusing for me to bother spending the time on to figure out how to use them just to download the data).

Data was saved here:

Generated MD5 checksums (using md5sum on Ubuntu) and appended to the checksums file:

Illumina was unable to provide MD5 checksums on their end, so I was unable to confirm data integrity post-download.

Illumina sample info is here:

Will add info to:

Assembly – Geoduck Hi-C Assembly Subsetting

Steven asked me to create a couple of subsets of our Phase Genomics Hi-C geoduck genome assembly (pga_02):

  • Contigs >10kbp

  • Contigs >30kbp

I used pyfaidx on Roadrunner and the following commands:

faidx --size-range 10000,100000000 PGA_assembly.fasta > PGA_assembly_10k_plus.fasta
faidx --size-range 30000,100000000 PGA_assembly.fasta > PGA_assembly_30k_plus.fasta

Ran Quast afterwards to get stats on the new FastA files just to confirm that the upper cutoff value was correct and didn’t get rid of the largest contig(s).

Results:

faidx Output folder: 20180512_geoduck_fasta_subsets/

10kbp contigs (FastA): 20180512_geoduck_fasta_subsets/PGA_assembly_10k_plus.fasta

30kbp contigs (FastA): 20180512_geoduck_fasta_subsets/PGA_assembly_30k_plus.fasta

Quast output folder: results_2018_05_14_06_26_26/

Quast report (HTML): results_2018_05_14_06_26_26/report.html

Everything looks good. The main thing I wanted to confirm by running Quast was that the largest contig in each subset was the same as the original PGA assembly (95,480,635bp.

Data Management – Geoduck Phase Genomics Hi-C Data

We received sequencing/assembly data from Phase Genomics.

The data contains two assemblies, produced on two different dates.

All data is here: 20180421_geoduck_hi-c

All FASTQ files (four files; Geoduck_HiC*.gz) were copied to Nightingales:

MD5 checksums were verified and appended to the Nightingales checksum file:

Nightingales sequencing inventory was updated (Google Sheet):

The two assemblies (and assembly stats) they provided are here:

I’ve updated the project-geoduck-genome GitHub wiki with this info.
