Retrieves stats from labels

Parameters
~~~~~~~~~~

name : string
    name of workflow
withreg : boolean
    indicates whether to register source to label

Example
~~~~~~~


Inputs::

       inputspec.source_file : reference image for mask generation
       inputspec.label_file : label file from which to get ROIs

       (optionally with registration)
       inputspec.reg_file : bbreg file (assumes reg from source to label
       inputspec.inverse : boolean whether to invert the registration
       inputspec.subjects_dir : freesurfer subjects directory

Outputs::

       outputspec.stats_file : stats file

Registers a source file to freesurfer space and create a brain mask in
source space

Requires fsl tools for initializing registration

Parameters
~~~~~~~~~~

name : string
    name of workflow
dilate_mask : boolean
    indicates whether to dilate mask or not

Example
~~~~~~~

>>> getmask = create_getmask_flow()
>>> getmask.inputs.inputspec.source_file = 'mean.nii'
>>> getmask.inputs.inputspec.subject_id = 's1'
>>> getmask.inputs.inputspec.subjects_dir = '.'
>>> getmask.inputs.inputspec.contrast_type = 't2'


Inputs::

       inputspec.source_file : reference image for mask generation
       inputspec.subject_id : freesurfer subject id
       inputspec.subjects_dir : freesurfer subjects directory
       inputspec.contrast_type : MR contrast of reference image

Outputs::

       outputspec.mask_file : binary mask file in reference image space
       outputspec.reg_file : registration file that maps reference image to
                             freesurfer space
       outputspec.reg_cost : cost of registration (useful for detecting misalignment)

Tessellates the input subject's aseg.mgz volume and returns
the surfaces for each region in stereolithic (.stl) format

Example
~~~~~~~
>>> from nipype.workflows.smri.freesurfer import create_tessellation_flow
>>> tessflow = create_tessellation_flow()
>>> tessflow.inputs.inputspec.subject_id = 'subj1'
>>> tessflow.inputs.inputspec.subjects_dir = '.'
>>> tessflow.inputs.inputspec.lookup_file = 'FreeSurferColorLUT.txt' # doctest: +SKIP
