I am trying to use BWA-MEM in Galaxy to align fastq files to mouse genome. I am having an issue with selecting the fastq dataset option. All fastq files have been uploaded to my history. How do I get the workflow to recognize these files?

Hello,

The datatype needs to be confirmed to be in Sanger Phred +33 format (or rescaled to that format) then assigned the .fastqsanger datatype.

How to: https://galaxyproject.org/support/#getting-inputs-right- >> How to format fastq data for tools that require .fastqsanger format?

Thanks! Jen, Galaxy team

Hi Jen, thanks for pointing me in the right direction. When I go to the Fastq Groomer function, I need to select the correct quality scores type, but there are only 4 listed and none of them is for Nanopore sequencing. Any idea what I should select? Just trying each one failed to have the command executed.

Hi Jen, I figured it out.

Christopher, Thanks for updating and glad you were able to sort this out! - Jen

Fastq data extracted from this data should already be in fastqsanger format, which means that the datatype .fastqsanger can be directly applied (no need to groom to transform quality score values).

But it is a good practice to check. Did the FastQC report guess that the (quality score) encoding was something other than "Sanger/Illumina 1.9"?
