Website overview

The Main / Home page

The main containts of the home page contain two main sections:

1. brief summary of db contents

This sections contain:

  • the main features of GMrepo
  • main contents of the database and links to the corresponding pages.

2. a graphic data selector

A graphic data selector that allows users to construct complex queries to the projects and runs in our database. It consists of two selectors, one is dedicated for searching for samples/runs, the other is for projects.

Below is a screenshot of the selector:


The search logic is to find runs/samples that are:

  • related to healthy individuals, AND,
  • 18 to 25 years old, AND,
  • with healthy BMI from 18.5 to 24.9.

See the Database usage section for details and more examples.

Header bar / navigation bar

The header bar is the most important widget of GMrepo.

It is fixed to the top so it is placed at the top of windows.

It plays three major roles, navigation and global search. See the screenshot below:

It displays a logo of GMrepo. Users can click this logo and navigate back to the home page .

It contains a global search widget that allows users to enter keywords of interests, shows the search results in a dropdown list, and allow users to click and go to the corresponding page in our database.

For example, users can use it to find any of the following entries in our database:

  • projects,
  • samples,
  • runs,
  • gut microbes,
  • marker microbes,
  • diseases and
  • disease-health comparisons


  • The search is automatic when users enter three and more characters, i.e., the search results (if there is any) will be shown automatically as users type. It is thus no need to press the "enter" key.

  • The wideget does not show anything is no maches are found in the database.

Please consult the help pages in the "Database usage" section for details.
