Hierarchical Data Format (HDF4) Files
Step 4: Importing Data and Metadata
To import the data set you have selected, click the Import button, bottom
right corner of the Importing and Subsetting pane. Using the Importing and
Subsetting pane, you can
• Specify the name of the workspace variable — By default, the HDF
Import Tool uses the name of the HDF4 data set as the name of the
MATLAB workspace variable. In the following figure, the variable name
is Example_SDS. To specify another name, enter text in the Workspace
Variable text box.
• Specify whether to import metadata associated with the data set — To
import any metadata that might be associated with the data set, select the
Import Metadata check box. To store the metadata, the HDF Import
Tool creates a second variable in the workspace with the same name
with “_info” appendedtoit. Forexample,if you select this check box,
the name of the metadata variable for the data set in the figure would be
Example_SDS_info.
• Save the data set import command syntax — The Dataset import
command text window displays the MATLAB command used to import
the data set. This text is not editable, but you can copy and paste it into the
MATLAB Command Window or a text editor for reuse.
The following figure shows how to specify these options in the HDF Import
Tool.
