BioMart help

The HGNC BioMart application allows users to create customised data tables without the need for any programming knowledge by interacting with a form to filter the data and select the columns/attributes they want within the table. This page details how to interact with the BioMart Mart form and provides definitions of the filters and attributes.

BioMart overview & project

BioMart is a generic data management system which offers a range of advanced query interfaces and administration tools.

The system comes with built-in support for query-optimisation and database federation. BioMart provides users with the ability to conduct fast, powerful queries using either web, graphical, or text based applications, or programatically using web service or software libraries written in Perl and Java. For data providers, the system simplifies the task of integrating their own data with other datasets hosted on the network.

All the software, including an easy to install BioMart website, is available for local installation. BioMart software is completely Open Source, licensed under the LGPL, and freely available to anyone without restrictions.

For more information about the BioMart project and to download the code visit the BioMart site.

HGNC Marts

The HGNC BioMart homepage provide a list of HGNC Marts that are available to use. By clicking on a Mart name the user will be taken to a mart form for the dataset of choice. So far we have two marts to choose from, a gene mart for gene symbol centric data and a family mart for the gene group centric data.

All the mart forms have the same template where the form is split into three parts, Datasets, Filters and Attributes.

Datasets

The datasets part of the mart form is for the user to select the database and the dataset they would like to query and download. The HGNC only have one database and so the database dropdown can be ignored. If the user has entered the site via the HGNC BioMart homepage the user will not have to change the dataset. However if the user has changed their mind and want to download data from another dataset the user can select a different dataset using the "Datasets" dropdown box which will change the form. As we have already mentioned we have two datasets to choose from so far, the gene dataset and the family/group dataset.

Filters

The filters section is an area for the user to filter the data by the provided fields. There are several types of filter for the user to interact with, the most common type being the text input filter. The filters are split into subsections, according to the type of field/data they filter. Filters are not required for a BioMart search. If a user wants to select attributes for all the data in the dataset they should ignore this section of the form.

Text input filters
Text input filters usually allow the user to add a wildcard "%" symbol to allow BioMart to search the field for data that is like the filter query. Text input filters have [wildcard = %] displayed in the label if wildcards are allowed.
Select box filters
Select box filters are easy to use in that all the user has to do is click on the filter and select the value to filter by. By default the filter will say "-- Select --" and by leaving it like this BioMart will ignore the filter.
Multiple select filters
Multiple select filters are scroll boxes that contain many values per line. To filter by a particular value the user can click on that value. If the user would like to filter on many values, a user using a windows computer should hold down the control (ctrl) key and click on another value. Mac users need to hold down the command (cmd) key instead.
Bulk upload filters
Our Mart forms also have bulk upload filters. The user first selects the field in which they would like to query multiple time by selecting a value within the drop down select box. The user can then place their values within the text area box or click the "upload file" link to select a file which contains the query values. All of the values have to be of the type selected within the drop down (i.e a user cannot provide a file or type in values that contain mixed ID/symbol/accession types).
