Data Type: Large Disk Data ()

Description:

A Large Disk Data object is useful for working with large image data. It allows you to extract subvolumes loaded as a normal field object. In this way can manage data that is larger than main memory. Note that only uniform coordinates are supported.

A selection of file formats can be loaded as Large Disk Data: ( data, Raw Data, Stacked-Slices, and Large Disk Data).

To access the data, you must attach an Access module. It provides an interface to load a subblock into . You can use all the visualization techniques on this subblock.

Like every other data object, a Large Disk Data object has parameters associated with it. In contrast to most other data types, the Large Disk Data cannot be saved directly. But some of the mentioned file formats allow you to save the actual parameters to the file defining the Large Disk Data. This is done by pressing the save parameters button. It is only visible if you have write access to the file.

The Save As menu entry allows export of the data into a common image file format or as raw data. It does not save parameters. This might seem strange at a first glance, but in contrast to all other data formats, the Large Disk Data values are not in main memory. The actual data resides only on disk and cannot be saved to another place by .
