Genes (RNA-Seq) on Oly Genome

Posted by & filed under Ostrea lurida.

We currently have a version (0.0.2) of the Ostrea lurida genome on CoGe. This is 38 scaffolds greater than 80k bp. Below is an effort to map gonad RNA-seq data to said genome. Two male gonad and two female libraries were mapped to the genome using TopHat in Cyverse Discovery Environment. Through the steps… I… Read more »

Getting back on tracks

Posted by & filed under Panopea generosa.

Yesterday I uploaded v0.0.1 of the Geoduck genome to CoGe. Now I want to start adding tracks. To do this I used CLC to create RNA-seq tracks from our male and female gonad transcriptome data. As would be expected only a small amount of reads mapped. This is as we are limiting the genome to… Read more »

First steps at an aggregated view of all DNA methylation data (updated)

Posted by & filed under Cgigas DNA Methylation.

Seems like I have gotten close (see here) but do not have a canonical IGV session that has all of our DNA methylation data. The goal here is to generate such a product (and publish, so I do not lose it). All data is publicly available at see also data on Figshare Updates July… Read more »

Splicing around

Posted by & filed under Cgigas DNA Methylation.

Here I am going to see to what degree I can identify differential splicing events that occur upon acute heat stress with the ultimate goal of determing if there is a relationship with differentiall splicing and DMLs. As the Tophat suite was used for RNA-seq, I will start exploring the cuffdiff output. Note all output… Read more »

RNA-Seq: Tophat via iPlant

Posted by & filed under Workflows.

Goal: Use RNA-seq to compare expression between oysters (n=3) pre and post heat shock. Based on IPlant Collaborative Tutorial Task 1: Align read data to Crassostrea gigas genome. Tophat is a specialized alignment software for RNA-seq reads that is aware of splice junctions when aligning to a reference assembly. 1) Click Apps from DE… Read more »
