Hi Ken,
<div class=""><br class="">
</div>
<div class="">I am a little puzzled. For Steven’s VTI file, each cluster/grain has a unique ID, for example: 3732, 3240, 4955, etc. When Paraview visualize this file, how does it place one grain next to each other, or how does it determine one grain is adjacent
to another? Is there any algorithm in paraview that defines adjacency? (I work in Research Computing center at UF and try to help Steven to run his program, so not really familiar with this work.)</div>
<div class=""><br class="">
</div>
<div class="">Thanks,</div>
<div class=""><br class="">
</div>
<div class="">Ying</div>

First, you just asked how ParaView will interpret this file. ParaView will read this as an "image" that is a regular 2D grid of data. It will show the data pretty much the same as the image below. (The colors will be different, but the meaning will be the same.)</div>

If you want to look at a single grain at a time, you can do that fairly easily with what is available in ParaView. You can either use the Threshold filter to extract a grain with a particular ID. Better yet, you can use the Find Data feature to select all "cells"
that belong to a particular grain. That will help you locate a grain in the image, where you can zoom in and manually peek at neighboring grains.</div>

Beyond that, you might need to design your own analysis algorithms. At this point, I'm not sure what you want to see. From an image processing point of view, your data is already classified since there is a unique identifier for each grain. You could write
a custom operation to identify all neighbors of all grains, but I'm not sure what you do with it after that.</div>
