@tmedani, can you let me know what OS did you have this issue?
I tested your data+script on Linux (Ubuntu 18.04) with MATLAB R2010 and R2020, as well as R2016 on Windows 10, in all 3 cases, the mesh was created correctly, with all 6 segments presented. see screenshots below.
I am using the latest git version of iso2mesh - I suppose the only difference is that for Windows, I added 64bit executables for all utilities on Windows, including tetgen1.5_x86-64.exe, about 3 months ago

can you try using the latest iso2mesh and see if it makes any difference?

Hi @fangq
I'm using windows 10 with Matlab 2019a,
I have updated the iso2mesh from the git and now it works fine.
That's great thank you.
However, I'm expecting 5 layers instead of 6,
something went wrong in the identification of the tissues.
I will check it.
Best,
from iso2mesh.
great. this makes sense now - when combining more surfaces, the memory demand of tetgen might have exceeded ~2GB and made 32bit binary crashed. A 64bit binary does not have that limit.
For the extra label, check to see if any of your surfaces have a closed compartment or two surfaces touching each other (like brain-stem), tetgen1.5 automatically label closed compartments if it sees one.
I will close this ticket for now.
