Module: Access Large Disk Data ()

Description:

This module is now deprecated.

This module is deprecated. Please use Extract Subvolume instead.

This kind of module is attached to a Large Disk Data object. provides an interface to select a subblock of the large volume which is stored on disk only.

You may select the volume either by typing in numbers to the ports or by using the blue dragger in the viewer.

Additionally, it is possible to request a lower resolution of the data. Dependent on the file format other resolutions are stored on disk and might be accessed rather fast or they are calculated on the fly which might take some time.

After selecting a volume you might press the Apply button. An field object is created and filled with the data from disk. You can now use all standard visualization techniques on this subblock.

If you check auto-refresh, you might change the selected volume and an immediate reload is started. This might be useful to easily explore a large volume.

Connections:

Data [required]
Connection to the Large Disk Data object.

ROI [optional]
If a ROI Box is connected it will define the subvolume to be loaded.

Ports:

Info

Indicates the size of the block to be loaded.

BoxMin

The position of the lower corner of the block. Printed as a lattice index.

BoxSize

The size of the block to be loaded. The size is in lattice indices in the base resolution. The numbers will not change if you select subsampling but the real size of the block to be loaded will change. This is indicated in the Info port.

Options

Hides the dragger and/or enables subsampling.

Subsample

Type in the number of voxels to be averaged in each dimension.
