See our [QC tutorial]({% link topics/sequence-analysis/tutorials/quality-control/tutorial.md %}#inspect-a-raw-sequence-file) for a more detailed explanation of encoding schemes.  Nowadays, the most commonly used encoding scheme is sanger. In Galaxy, this is the `fastqsanger` datatype. If you are using older datasets, make sure to verify the FASTQ encoding scheme used in your data.  **Be Careful: choosing the wrong encoding scheme can lead to incorrect results!**  **Tip:** There are 2 Galaxy datatypes that have similar names, but are not the same, please make sure you `fastqsanger` and `fastqcssanger` (not the additional `cs`).  **Tip:** When in doubt, choose `fastqsanger`   ","height":400,"html":"<iframe width=\"560\" height=\"400\" scrolling=\"yes\" sandbox=\"allow-same-origin allow-scripts\" title=\"FAQ: FASTQ files: `fastq` vs `fastqsanger` vs ..\" src=\"https://training.galaxyproject.org/training-material/faqs/galaxy/datatypes_fastq_varieties.html?utm_source=galaxy-help&utm_medium=oembed&utm_campaign=oembed\" frameborder=\"0\" allowfullscreen></iframe>","provider_name":"Galaxy Training Network (GTN)","provider_url":"https://galaxy.training","thumbnail_height":400,"thumbnail_url":"https://training.galaxyproject.org/training-material/assets/images/GTNLogo1000.png","thumbnail_width":560,"title":"FAQ: FASTQ files: `fastq` vs `fastqsanger` vs ..","type":"video","version":"1.0","width":560}
