Welcome, @OSIRIS!

I’m guessing that you need `FASTA` format? If yes, try the tool: `Convert Formats` \> `FASTQ to FASTA converter`.

If you instead need `FASTQ` format, the current format should be supported by the tool (if not, we would be curious about which is presenting with the input problem/rejection). `Fastqsanger` is a subtype of `FASTQ` format and, importantly, the subtype that is required by most Galaxy wrapped tools.

FAQs (with more here: [https://galaxyproject.org/support](https://galaxyproject.org/support))

- [Common datatypes explained](https://galaxyproject.org/learn/datatypes/)

If that doesn’t help, please explain more about your goals/inputs.

Thanks!

Thanks jennaj, I was so happy cause I found in Galaxy a way to convert my sequences in format fastq.gz when I splitted them into 16s and 18s. But my file didn’t work; my sequences looks good in galaxy plataform (fast.gz), but winrar, winzip, 7z couldn’t open, I don’t know why ☹ it said that my file is damage.

It sounds like the `.gz` compression is not compatible for some reason. Uncompress the data in Galaxy, then download it in that format. You can always compress again using Window tools after.

Use `curl` or `wget` to get larger datasets. FAQ: [Downloading Data](https://galaxyproject.org/support/download-data/)
