The HDF Loader add-on can load 1D, 2D, and 3D Scientific Data Sets (SDS) from HDF files1. When a dataset from an HDF file is imported, the file is scanned and a list of all SDS in the file is displayed in the Scientific Data Sets to load portion of the HDF Loader dialog. Select one or more SDS to import. Every SDS that you select must have the same dimension. A rectangular I, IJ, or IJK-ordered zone (for 1, 2, or 3D data, respectively) is created for each SDS that you select to load.
The HDF Loader dialog has the following options:
• Scientific Data Sets to load - Select one or more SDS's to load. Each SDS that you select must have the same rank (dimension).
• I-Skip - Select the I-Skip value. A skip value of one loads every data point, a skip value of two loads every second data point, and so on.
• J-Skip - Select the J-Skip value.
• K-Skip - Select the K-Skip value.
• Select File - Select an HDF file.
• Attributes - Displays attributes of each SDS found, such as number type, rank, label, and so on.
You may also click Select File to choose a different file.
4 - 17.1 HDF Loader Limitations
The HDF Loader can import only Scientific Data Sets from HDF files, and these are imported in a manner similar to NCSA's own HDF viewer. The way in which the data file is interpreted cannot be altered in this release of the loader.
