Searching and visualising data from the EBI Metagenomics resource
This section consists of multiple pages. Use these links to navigate
Simple text search
You can access public metagenomic and metatranscriptomic projects or samples via the ‘Project’ or ‘Samples’ navigation tabs, using either their accession number or via plain text search (Figure 2a). The resulting lists can be filtered to narrow down the information shown; for example, searching with a word or phrase (e.g. “Gut”) will show only those projects or samples with metadata containing that term.
Figure 2 a) Simple search text fields allow easy sample searching on the 'Projects' and 'Samples' pages.
Project Overview page
A project is defined as a collection of samples and a sample is defined by a data file (in FASTQ or SFF format). The ‘Project’ tab shows the list of projects that are accessible and the number of samples associated with each project. Clicking on a particular project name will display the ‘Project Overview’ page, where a description of the project, links to any related publications and contact details for the submitter are provided (Figure 2b).
The samples associated with the project are listed, with links to the ‘Sample Overview’ and ‘Sample Analysis’ result pages. You can also directly access the sample information by searching in the ‘Samples’ tab and clicking through from there.

Sample Overview page
The ‘Sample Overview’ page displays the sample description and other associated metadata (Figure 2c).

Sample Analysis page
The ‘Sample Analysis’ page includes general statistics about the sequences that have been determined from the sample, protein function analysis results and a representation of the distribution of GO terms, corresponding to biological process, molecular function and cellular components in the annotation (Figure 2d).
