What is FastQC file?

FastQC, written by Simon Andrews of Babraham Bioinformatics, is a very popular tool used to provide an overview of basic quality control metrics for raw next generation sequencing data. In addition to the graphical or list data provided by each module, a flag of “Passed”, “Warn” or “Fail” is assigned.

What are the functions in Galaxy SAMtools?

SAMtools – various utilities for manipulating alignments in the SAM/BAM format, including sorting, merging, indexing and generating alignments in a per-position format. BAMtools – a toolkit for reading, writing, and manipulating BAM (genome alignment) files.

Which Galaxy Tool can be used to assess the quality of a Fastq file?

FastQC , the tool we will use in the next step, can be used to try to determine what type of quality encoding is used (through assessing the range of Phred values seen in the FASTQ). When looking at the file in Galaxy, it looks like most the nucleotides have a high score ( I corresponding to a score 40).

How do I use Samsung Galaxy server?

At the end of the course, you will be able to:

  1. login to a Galaxy server.
  2. upload data to a Galaxy server from:
  3. A file on your local computer.
  4. A file on a remote datastore with an accessible URL.
  5. use tools in Galaxy by:
  6. Accessing the tool via the tool menu.
  7. Using the tool interface to run the particular tool.

When should I use FastQC?

FastQC provides a simple way to do some quality control checks on raw sequence data coming from high throughput sequencing pipelines. It provides a modular set of analyses which you can use to give a quick impression of whether your data has any problems of which you should be aware before doing any further analysis.

What is a good Phred quality score?

For many purposes, a Phred Score of 20 or above is acceptable, because this means that whatever it qualifies is 99% accurate, with a 1% chance of error.
