1. ChP_segmentation script
   The ChP segmentation algorithm
   The path to the image data need to be write into path=dir('path to image data')
   obr: containes loaded image stack
   chp_AC_art_rem_filtered: final segmentation
2. volume_surface_angle script
   The volume,surface area and angle is computed 
   The resulting values are further analyzed 
3. quantitative_analysis function
   function which computes volume, surface area and angle; volume and area are converted into radius
   image_path = path to the trimmed dataset. The data trimming was done in main ChP script
   mask_path = path to the tiff ChP masks hich were trimmed, thus only the 4th ventricle region is included;
   VoxelSize = voxel size of loaded data
4. GPA_PCA script
   The script performs the GPA calculation. The Procrustes distances are computed. The results are further analyzed using PCA and clustering. 
   The landmarks are included within the script. The LM were manually chosen using 3D Slicer.
