Import HDF5 Data

Hierarchical Data Format, Version 5 (HDF5) is a portable file format for storing data. An HDF5 file consists of groups and datasets. When you import the file, JMP opens a group to present the names of the inner datasets. For example, if the file contains data for a group of musical recordings with songs and artists tables, JMP prompts you to open either “songs” or “artists”. If the file does not contain a group, JMP prompts you to open a single table.

JMP handles only tables with numeric (integer, float, double) and string types, and compound files with three or fewer dimensions that contain only simple types. If a data set does not appear in the import window, the file is most likely unsupported.

You can import up to 1,000,000 columns and an unbounded number of rows.

Note: Only ASCII characters are supported in HDF5 files. Non-ASCII characters such as French and Chinese characters are not supported.

To import an HDF5 file, follow these steps:

1. Select File > Open.

2. On Windows, make sure that All JMP Files or HDF5 Data File is selected from the File name list.

3. Select the HDF5 file.

A list of groups or datasets in the file appears.

4. Select the data set that you want to import and click Import.

The data are opened as data tables.
