Whether you’re a scientist, a bioinformatician, a data scientist, or a member of the general public looking for data, data on the NF Portal can be explored and accessed in multiple ways. The portal offers helpful filtering tools to help you find data of interest. All of the data and resources uploaded into the portal are labelled with metadata and annotations, so they can be easily used to help query the list of resources in each page. You can find a detailed breakdown of metadata definitions and explanations in our metadata dictionary.

To help explain how to use these sections, refer to the following bullet points and the corresponding image below:
red arrows → When exploring the Files subtab, the Filter Data By sections that appear by default are: Assay, Data Type, and Tumor Type
red rectangle → There are various other categories that you can expand and filter by as well—click the plus sign next to any of these (File Format, Funding Agency, Individual ID, NF1 Genotype, NF2 Genotype, etc.) to reveal its filtering options
red circles → At the end of each category, click on Show more to reveal all filters for that category

For example, when exploring the File subtab, the following Filter By sections appear by default: Assay, Data Type, and Tumor Type. Then, there are more than a dozen additional categories that you can expand and filter by as well. Click the plus sign next to any of these (File Format, Individual ID, Species, etc.) to reveal its filtering options. At the end of each category, click on Show more to reveal all filters for that category.Notice how, by default, each of the categories have a checkmark in the box labelled All—since no filters have been applied for that . Before you apply any filters for a category, it will includes all files within that category until a filter(s) is applied. Next to each filtering option is a number—this indicates how many files will be included in that specific filter. For example, looking at the image above, if you check the rnaSeq box under the Assay section, the files will be narrowed down to 3,802 results, as seen in the image below.
...
Selecting filters from more than one category will quickly further narrow down the results down more. For example, if I also you were to check the geneExpression boxfrom the Data Type section and Schwannoma fro from the Assay section, I’m left with only 4 results of data.You can mix and match Tumor Type section (in addition to the rnaSeq filter), your results would be narrowed down to 657, as seen in the image below.
...
You can play around with the filtering options as you wish to narrow down the search down to and find your data of interest. Each additional filter will appear in the section under the graphs—you can easily remove individual filters as necessary, or click Clear All (top right) to remove all filters and start over.Continue reading about how the resulting data is displayed in the visualizations and table, or visit this page for information on how to download data.
Visualizations
This section of graphs at the top of the page will display visualizations for each category according to the data you’ve filtered. You can use the filter icon (3️⃣) for any graph chart to adjust the filters for that category—this will change the results as a whole (not just for that graphchart), just as it would if you changed the filters under Filter Data By.
Use the expand icon (6️⃣) to make that specific graph chart bigger and the contract icon (inverse of 6️⃣) to return back to normal size.Click the X is(7️⃣) to temporarily remove that graph from view.
By default, the graphs charts displayed are for the categories Study, Assay and Data Type, and Assay. Click Show All Graphs VIEW ALL CHARTS to display graphs charts for all categories, and Hide Optional Graphs HIDE CHARTS to restore the default display.
Click the X (7️⃣) next to any chart to temporarily remove that chart from view.
Data table
The data that you’ve filtered for will appear in the data table below the visualizations section. Notice how it’s organized by category—you can use the filter icon (3️⃣) next to any category header to change the filters, just as it would if you changed the filters under Filter Data By. Use the reorder icon (8️⃣) next to any of the category headers to rearrange the table data in reverse based on that category.
