Hello All,

I am currently having trouble with the BoneTexture Extension and was hoping that someone may be of help. I have a cranium that I have segmented into 8 segments, and I would like to use the BoneTexture extensions “Compute BM Features” to compute BV/TV, etc for each of the 8 segments. I have created the segments and exported them as a binary label map. I then put the master scan for the “input scan” and would like to use each of the segments as the “mask”, however when I do so, I get the same result for each segment. Is this because slicer is exporting all the segments into a single binary label map when I do the export? Is there a way to do this? It’s a very critical part of my research project, so any help whatsoever would be greatly appreciated.

Take good care,

Jamie

I found a workaround shortly after I posted! If you hide all segments except for the one you want to export to a binary label map and do that for each segment respectively, then you will be able to compute the BM features for each segment individually.

If you need analyze many images then you can automate these steps by a short Python scripts. Even better, you could update the Python script that [BoneTexture analysis Python script](https://github.com/Kitware/BoneTextureExtension/blob/master/BoneTexture/BoneTexture.py) to iterate through all the segments and report results for each.

I’m very, very, (very) novice when it comes to Python so I’m in a situation when the time to do it manually may be = to the time it would take to run the scripts. I’ll take a whack at it though! Thank you!
