Lung volume measurement

Hello
I wanted to use the LungCTAnalyzer for lung volume measurement.
I followed the instructions provided on Github, but when I reviewed the results, the lung volume, and a few other values seemed wrong.

On the Log:

1. [WARNING][VTK] 22.09.2024 16:24:48 [vtkMRMLMarkupsFiducialNode (000002329D09EFB0)] (vtkMRMLMarkupsFiducialNode.h:119) - vtkMRMLMarkupsFiducialNode::AddFiducialFromArray method is deprecated, please use AddControlPoint instead

2. Generic Warning: In vtkSlicerMarkupsToModelClosedSurfaceGeneration.cxx, line 311
Extent ranges not provided in order largest to smallest. Unexpected results may occur.

3. [WARNING][VTK] 22.09.2024 16:21:20 [vtkOpenGLVolumeOpacityTable (0000023335C918B0)] (vtkOpenGLVolumeLookupTable.cxx:88) - This OpenGL implementation does not support the required texture size of 65536, falling back to maximum allowed, 16384.This may cause an incorrect lookup table mapping.

The problem, I guess, is similar to what one of the other researchers had before LungCTAnalyzer extension for lung CT segmentation and analysis for COVID-19 assessment - #30 by mahmoud.

On the demo model, everything works perfectly. Is this potentially because of the resampling?

Thanks
