The Metadata Utility can facilitate the creation of the tab-delimited text files for an ISA archive. This page describes how to import these files for continued development. The terminology in this utility reflects that these files represent an investigation.

1. Start the Metadata Utility, as described in Starting the Metadata Utility.
