Click the File | Import command, click the button, right-click in the Network Manager and choose Import, or double-click Import in the Module Manager to load a data file into a data source module. Depending on the format of the data, one or more format-specific dialogs may appear. The loaded data displays as a new icon in the Network Manager. It can then be connected to other modules in the network.


When this command is selected, the  Import dialog displays, allowing one or more files to be selected and loaded. Each data set from each file is loaded into its own source module. Multiple data files can be loaded at once by pressing the SHIFT or CTRL keys while selecting files in the dialog.


The Import Dialog

The File | Import command opens the Import dialog.


Specify files to import using the Import dialog.


The Import dialog has the following options available:


Look In

The Look in field shows the current directory. Click the down arrow to see the directory structure; click the folders to change directories.


Creating New Folders and Changing the View

The buttons to the right of the Look in field allow you to create new folders and change the view of the file list.


File List

The File list displays files in the current directory, which is listed in the Look in field. The File of type field controls the display of the file list. For example, if Voxler Project Files (*.voxb) is listed in the Files of type field, only *.VOXB files appear in the files list.


File Name

The File name field shows the name of the selected file. Type a path and file name into the box to open a specific file.


Specify a File Type

The Files of type field controls the display of the file list. For example, if Voxler Project Files (*.VOXB) is listed in the Files of type field, only .VOXB files appear in the file list. To see all files in the directory, choose All Files (*.*) from the Files of type list. Double-click a file to open it, or click the file once and then click the Open button.


The Files of type field shows the file format to be imported. To change the file format, click the down arrow and select the file type from the list. All Files (*.*) displays all files in a directory.


Open or Cancel

Click Open to close the Open dialog and import the specified file. Click Cancel to close the dialog without opening a new file.


Data Import Options Dialog

The Data Import Options dialog appears only once, even if more than one file is selected. Any changes made in this dialog are automatically applied to all files. If you need to specify different import options for one or more files, you must load them individually.  


File Formats

Voxler automatically attempts to determine the selected file formats. The format of the imported file(s) is determined as follows:

  1. If a particular format is specified in the Files of type list of the Import dialog, that format is used.

  2. If that fails, then a match is made by using the file extension.

  3. If the format still cannot be determined, the Select Format dialog displays and you are prompted to select the format from a list of supported formats.


Data Types

Voxler supports several different types of data:

Loading Multiple Images

Image stacks are loaded as a three-dimensional lattice. These are usually a series of planar image slices that are meant to be stacked one on top of another to form a three-dimensional volume. The individual slices are often in a standard two-dimensional format like .TIFF, .JPEG, or .DICOM. This type of data is commonly created by medical imaging equipment.


If all of the images are selected at once and the sizes are identical, Voxler attempts to combine them into a single three-dimensional lattice. The slices are combined in alphabetical order according to the file names. The stacking starts at the bottom (Z=1) and proceeds upward. Simultaneous selection is most easily achieved by first clicking the first slice and then holding down the SHIFT key and clicking the last slice. The resulting source module takes the name of the first loaded image. The name of the last file is listed next to File Path in the Property Manager.


Image Coordinates

When loading image bitmap files with coordinates, the coordinate information comes from a geotiff (internal information) or external files.
