Earlier this week, I ran TrimGalore!, but set the trimming, incorrectly – due to a copy/paste mistake, as --non-directional, so I re-ran with the correct settings.

Steven requested that I trim the Geoduck RRBS libraries that we have, in preparation to run them through Bismark.

These libraries were originally created by Hollie Putnam using the TruSeq DNA Methylation Kit (Illumina):

• project_juvenile_geoduck_OA/Sample_Processing (GitHub)

All analysis is documented in a Jupyter Notebook; see link below.

Overview of process:

1. Run TrimGalore! with --paired and --rrbs settings.

2. Run FastQC and MultiQC on trimmed files.

3. Copy all data to owl (see Results below for link).

4. Confirm data integrity via MD5 checksums.

Earlier today I finished trimming Hollie’s RRBS BS-seq FastQ data.

However, the original files were never analyzed with FastQC, so I ran it on the original files.

These libraries were originally created by Hollie Putnam using the TruSeq DNA Methylation Kit (Illumina):

• project_juvenile_geoduck_OA/Sample_Processing (GitHub)

FastQC was run, followed by MultiQC. Analysis was run on Roadrunner.

All analysis is documented in a Jupyter Notebook; see link below.

20180516 – UPDATE!!

THIS WAS RUN WITH THE INCORRECT SETTING IN TRIMGALORE! --non-directional

WILL RE-RUN

MultiQC report (HTML):

Yesterday, I downloaded the Illumina FASTQ files provided by Genewiz for Hollie Putnam’s reduced representation bisulfite geoduck libraries. However, Genewiz had not provided a checksum file at the time.

I received the checksum file from Genewiz and have verified that the data is intact. Verification is described in the Jupyter notebook below.

Data files are located here: owl/web/nightingales/P_generosa

Jupyter notebook (GitHub): 20161230_docker_geoduck_RRBS_md5_checks.ipynb

Hollie Putnam prepared some reduced representation bisulfite Illumina libraries and had them sequenced by Genewiz.

The data was downloaded and MD5 checksums were generated.

IMPORTANT: MD5 checksums have not yet been provided by Genewiz! We cannot verify the integrity of these data files at this time! Checksums have been requested. Will create new notebook entry (and add link to said entry) once the checksums have been received and we can compare them.

UPDATE 20161230 – Have received and verified checksums.

Jupyter notebook: 20161229_docker_genewiz_geoduck_RRBS_data.ipynb

Hollie Putnam asked me to help her get samples ready for submission for Illumina sequencing at Genewiz.

She had previously prepared reduced representation bisulfite libraries on 20161215.

She also prepped a whole genome library on 20161201 – specifically sample EPI_135 WG.

She needed these samples combined in to four separate pools. However, Pool 5 was to be pooled with a total of five samples, including EPI_135 WG. She asked that the EPI_135 WG sample make up 50% of the DNA in the pool.

Using her previously determined sample concentrations, I pooled the libraries in equal quantities.

Calculations (Google Sheet): 20161219_hollie_library_pool_calcs

The pool volumes are high and, the calculated pool concentrations are low. Due to time limitations on our end, it was not feasible for me to SpeedVac these down to achieve the target concentration of 10nM. I’ve notified Hollie and asked her to see if Genewiz will perform that service.

Samples were shipped on dry ice to Genewiz via FedEx Standard Overnight.
