[Steven asked me to evaluate our methylation sequencing data sets for Olympia oyster](https://github.com/RobertsLab/resources/issues/225).

According to our [Olympia oyster genome wiki](https://github.com/RobertsLab/project-olympia.oyster-genomic/wiki), we have the following two sets of BS-seq data:





  * [Whole genome BS-seq (2015)](https://github.com/RobertsLab/project-olympia.oyster-genomic/wiki/Whole-genome-BSseq-December-2015)



  * [MBD BS-seq (2015)](https://github.com/RobertsLab/project-olympia.oyster-genomic/wiki/MBD-BSseq-December-2015)






All computing was conducted on our Apple Xserve: `emu`.

All steps were documented in this Jupyter Notebook (GitHub): [20180503_emu_oly_methylation_mapping.ipynb](https://github.com/sr320/LabDocs/blob/master/jupyter_nbs/sam/20180503_emu_oly_methylation_mapping.ipynb)

NOTE: The Jupyter Notebook linked above is very large in size. As such it will _not_ render on GitHub. It will need to be downloaded to a computer that can run Jupyter Notebooks and viewed that way.

Here's a brief overview of what was done.

Samples were trimmed with TrimGalore and then evaluated with FastQC. MultiQC was used to generate a nice visual summary report of all samples.

The Olympia oyster genome assembly, [pbjelly_sjw_01](https://github.com/RobertsLab/project-olympia.oyster-genomic/wiki/Genome-Assemblies), was used as the reference genome and was prepared for use in Bismark:


<pre><code>
/home/shared/Bismark-0.19.1/bismark_genome_preparation \
--path_to_bowtie /home/shared/bowtie2-2.3.4.1-linux-x86_64/ \
--verbose /home/sam/data/oly_methylseq/oly_genome/ \
2> 20180507_bismark_genome_prep.err
</code></pre>



Bismark was run on trimmed samples with the following command:
