Hi Giuseppe,

many thanks for your help and availability. We also can produce the .vxl file and visualize it in the flair interface without errors or warning. However, the main issue is that the simulation does not run and we always get the following error in the *.out file (here attached):

    !!!!!!!!!!!!! WARNING !!!!!!!!!!!!!!!

   Region # 2 in the voxel geometry has no
   corresponding voxel/organ, no way to continue

Abort called from VXLBDY reason NO NR_TH VOXEL FOUND Run stopped!
STOP NO NR_TH VOXEL FOUND


many many thanks again,
best regards,
Daria

Hi Daria
I succeeded to import your CT, create the vxl and visualize it at the
first attempt.
I attach the input file, the flair project, a 3D image of geometry (is
that what you expect?) and a screenshot of Flair.
Take care of having the voxel file (mice.vxl) in the same directory
where you have TEST.inp (not a subdirectory).
I assume that you know that the voxel file can be visualized only in the
"lattice" or "3D" layers of geometry visualizer. In the 3D layer you
need to tick off the Edge Detection option.
