This script runs the dHCP structural pipeline.

Arguments:
  subject_ID                    subject ID
  session_ID                    session ID
  scan_age                      Number: Subject age in weeks. This is used to select the appropriate template for the initial registration. 
                                If the age is <28w or >44w, it will be set to 28w or 44w respectively.
  -T2 <subject_T2.nii.gz>       Nifti Image: The T2 image of the subject
  -T1 <subject_T1.nii.gz>       Nifti Image: The T1 image of the subject (Optional)

Options:
  -d / -data-dir  <directory>   The directory used to run the script and output the files. 
  -additional                   If specified, the pipeline will produce some additional files not included in release v1.0 (such as segmentation prob.maps, warps to MNI space, ..) (default: False) 
  -t / -threads  <number>       Number of threads (CPU cores) used (default: 1)
  -no-reorient                  The images will not be reoriented before processing (using the FSL fslreorient2std command) (default: False) 
  -no-cleanup                   The intermediate files produced (workdir directory) will not be deleted (default: False) 
  -h / -help / --help           Print usage.
