There are multiple methods to retrieve sequencing data, from simple tools like NCBI’s Galaxy to the relatively more complex, Linux CLI. Shotgun metagenomics often generates substantial data, so be prepared for a sizable download. Several tools are available for you to access metagenomic data. Select the method that aligns with your familiarity and preferences, ensuring you have the necessary software (like the SRA Toolkit) installed if you opt for command-line downloading.

You can locate relevant data by referencing a specific paper you’re interested in and checking the availability of the data. Let’s consider [PRJNA834801](https://www.ncbi.nlm.nih.gov/bioproject/PRJNA834801/). This public study by Dr. Wallen and their team covering Parkinson’s disease will be used as an example.
