About FLink
  FLink icon FLink is a tool that enables you to traverse from a group of records in a source database (e.g., Proteins) to a ranked list of associated records in a destination database (e.g., BioSystems).

The name "FLink" is based on the German word meaning nimble, swift, agile, reflecting the tool's purpose to process large quantities of input and output (up to 100,000 UIDs in each) in an efficient and meaningful way. The name is also an abbreviation for "frequency-weighted links" because the records in the destination database are ranked by the number of items from the source database to which they are linked, as shown by the "frequency" column in the illustration below.

The help document includes a quick start guide that shows the easy 1-2-3 step process for using the tool, and provides additional details about proper formatting of the (1) input UID list and features of the (2) review + select display and (3) output display.

Although FLink icon FLink was initially developed as a companion tool for the BioSystems database in order to input a list of proteins, genes, or small molecules and retrieve a ranked list of biosystems, it can also be used in a similar way for other types of input and output data, as noted in the list of FLink's supported databases.

Step 2 in using FLink: Review your input list and use the LinkTo menu option to select a destination database.  Click on this graphic to read more details about this display, the JobID you'll receive after using the LinkTo option, and folder tab functions. Step 3 in using FLink: View the output, which displays a ranked list of records from destination database. The frequency column shows the number of items from your input list that are linked to each retrieved record.
