Filtering results

Within the search results page, users can narrow the results based on a number of different fields. On the left side of the page, view the available filters to narrow down the search. Shown in parentheses is the number of records with that particular value.

Searching for HIV/AIDS yields results on the right and a filters panel on the left..

For example, if a researcher wanted to narrow the search for HIV / AIDS data to only include Genome binding/occupancy profiling by high throughput sequencing datasets from NCBI GEO, they could select the "NCBI GEO" checkbox under Source and "Genome binding/occupancy profiling by high throughput sequencing" under Measurement Technique. This will update the search results and the count of records in the filters.

At the top of the page there are buttons for the filters applied; clicking on the "X" will remove that particular filter.

Each filter applied has a filter tag associated with it.

📘 What happens if I select multiple items from the same group or different filter groups?

Selecting items from multiple filter groups looks for both of those filters

Selecting checkboxes from two separate filters — like Source and Measurement Technique in the example above — will provide only the records which fulfill both those conditions, like NCBI GEO and Genome binding/occupancy profiling by high throughput sequencing.

Selecting within a group looks for any of those filters

Selecting multiple Measurement Techniques, for example, would look for either of those conditions, like Genome binding/occupancy profiling by high throughput sequencing or CyTOF.

What can I filter by?#

Date#

Describes the most recent date from date created, modified, or published. Use the date histogram to filter by year or filter to a date range by manually entering a start and end date and hitting 'Submit.' The results will automatically include all records that do not contain date metadata until you apply a date filter or deselect 'Include resources with no date information.'

Health Condition#

Use the Health Condition filter to narrow down the health conditions or infectious diseases which are the focus of the datasets. For example, a researcher could use this filter to quickly find all datasets where 'tuberculosis' is listed as the health condition.

Pathogen#

Use the Pathogen filter to narrow down the infectious agents or pathogens which are the focus of the datasets. For example, a researcher could search for influenza datasets and filter by just 'h1n1 subtype' or 'h5n1 subtype.'

Species#

Use Species to filter by the species or host organisms from which the datasets have been collected. For example, a researcher could narrow their search for COVID-19 datasets to 'homo sapiens' if they are only interested in human data.

Source#

Use the Source filter to narrow down where the original metadata comes from. This is a required field for every record. See Where does the data come from?

Funding#

Use Funding to filter by the funding agency and/or grant number that help fund the dataset creation. Multiple grants/contracts/awards can apply to a given record, and often, the funding information is missing for a record.

Conditions of Access#

Use Conditions of Access to filter by dataset accessibility. Datasets may be open, closed, or have restricted or embargoed access. This information may also be missing for many records.

Variable Measured#

Use the Variable Measured filter to narrow results to specific variables measured by datasets. Each record may have one, many, or no variable measured metadata associated with it. For example, a researcher could narrow their search for malaria to proteomics datasets.

Measurement Technique#

Use Measurement Technique to filter by the experimental or analytical techniques used to generate datasets. Each record may have one, many, or no measurement techniques associated with it. For example, a researcher could filter their influenza search to flow cytometry datasets.

Searching within a filter#

There is a search bar within each filter to find particular terms. For example, a user could open the Measurement Technique panel and enter "sequencing" in the search bar to list only the measurement techniques related to sequencing.

Selecting 'Not specified'#

Metadata does not exist for many fields in every record. Within each filter, select 'Not specified' to get all of the results for a query that do not have metadata for that field. For example, if a researcher was interested in influenza prevalence in dogs and found that the Species filter had 6 results for Canis lupus familiaris, they could select "Not specified" to search across the remaining records to see if there are additional relevant datasets.
