class smriprep.interfaces.freesurfer.MakeMidthickness(**inputs)[source]

Bases: MakeMidthickness, FSCommandOpenMP

Wrapped executable: mris_expand.

Patched MakeMidthickness interface

Ensures output filenames are specified with hemisphere labels, when appropriate. This may not cover all use-cases in MRIsExpand, but we’re just making midthickness files.

This interface also sets the OMP_NUM_THREADS environment variable to floor(1.5x) the number of threads requested by the user, as tests indicate that cores are underutilized by a factor of 2/3.

>>> from smriprep.interfaces.freesurfer import MakeMidthickness
>>> mris_expand = MakeMidthickness(thickness=True, distance=0.5)
>>> mris_expand.inputs.in_file = 'lh.white'
>>> mris_expand.cmdline
'mris_expand -thickness lh.white 0.5 lh.expanded'
>>> mris_expand.inputs.out_name = 'graymid'
>>> mris_expand.cmdline
'mris_expand -thickness lh.white 0.5 lh.graymid'

Explicit hemisphere labels should still be respected:

>>> mris_expand.inputs.out_name = 'rh.graymid'
>>> mris_expand.cmdline
'mris_expand -thickness lh.white 0.5 rh.graymid'
