1. Prerequisites

Your NCI account should be connected to NCI project "fx2" to obtain the example data set.

2. Import Data

Follow steps in Drishti on Gadi via ARE VDI to start Drishti Launcher.

Start Drishti Import from Drishti Launcher to import data from /g/data/fx2/public/fossils/Griphognathus_mandible

Load → Directory → NetCDF Directory

Select tomo2048W.nc directory.  This directory contains the volumetric data to be imported.

You can also drag-and-drop tomo2048W.nc directory into Drishti Import.  If done this way, a dialog will pop up to ask for the type of directory.  Select NetCDF Directory from drop-down options.

As the volumetric data is read from the directory its histogram is calculated.

Hover over the Histogram color gradient and press Space Bar to bring up color options.

Select orange-yellow-blue color scheme.

Change the value mappings and select required sub-volume to save.

Files → Save As to save the selected data in your area.  Select OK for all the options that follow.

This will create two files .pvl.nc and .pvl.nc.001.

3. Visualize Data

Start Drishti from Drishti Launcher to visualize the imported data.

File → Load Volume → Load 1 Volume to load the .pvl.nc file just created via Drishti Import.

Alternatively, drag-and-drop the .pvl.nc file in Drishti.

Press F2 to switch to high resolution mode.

Enjoy exploring the data.
