INA offers several options to import data and several interfaces are adapted to ingest data from files downloaded from ESA and/or NASA databases devoted to Cluster, ACE, Venus Express and Ulysses data.
A tutorial on how to import data with INA is available here: INA_Tutorial1_IMPORT_v2.pdf.
The data import functionality is divided into four levels giving the user the chance to choose the Data Type (from spacecraft, from file, synthetic, other) -> Mission -> Experiment -> Data Source as shown in the diagram below:
The user is guided through several steps to define the data type to be ingested by INA until it finally selects the data file stored locally, as suggested by the screenshot shown below
