ATAC-seq analysis and tutorial

Hi there,

I’m following the tutorial for ATAC-seq analysis for the platform. They use Genrich for peak calling but it doesn’t show up when I look for it in “tools”. Isn’t it available yet?

Thanks!

Welcome @Chiqui

Not all tools are available at all public Galaxy servers. Some are domain-specific. Some have unique tools. If running your own server, tools are usually in the ToolShed https://usegalaxy.org/toolshed and can be installed, but not always.

That is a lot of “sometimes”. So let’s break this down into smaller pieces and work on a solution from there. Specifically, these details would help:

  1. What exact tutorial are you following? Link/URL?

  2. Which Galaxy server are you currently working at? URL please if public. Describe the source/server type if not public (it is Ok if you don’t know the non-public full details, just share what you can).

Thanks!

Hi! Thanks for the reply!

  1. I’m following this tutorial: https://galaxyproject.github.io/training-material/topics/epigenetics/tutorials/atac-seq/tutorial.html
  2. I’m using the web-base platform (usegalaxy.org) so it seems it works with CyVerseat the Texas Advanced Computing Center

Is there any other way to work with Galaxy in a user-friendly manner that doesn’t depend on the website? I am not a bioinformacitian and even though I have some knowledge of R, it’s hard for me to analyze data using scripts. That’s why I was amazed when I found and started using the website.

Well, I hope you can help me!

Best!

Hi,
I am very happy to see that this tutorial is used.
When you go to the tutorial webpage, in the overview frame, you have an icon written Galaxies. If you click on it, you will see where you can run the full pipeline. As you will see, you can run it on usegalaxy.eu.

I hope it helps,

Best

Welcome @Tini

How and if to trim adaptor depends on your fastq read data content.

Review your FastQC as shown in the tutorial – were any detected? You can post back a screenshot if you want.

Thanks this is what i got in the FastQC.

This is the same adapter as in the tutorial, so you can use the same adaptor sequence and follow the instructions exactly.
