The output network will include the following summaries of your dataset:
Load an NSF file into the tool, then create a database from it using the NSF database loader?.
For a quick analysis of a small dataset you may wish to merge together investigator entities with identical names. For a scientifically sound analysis of a larger dataset, you can create custom merging orders and perform the merge.
