Paint¶
Wraps command mrisp_paint
This program is useful for extracting one of the arrays (“a variable”) from a surface-registration template file. The output is a file containing a surface-worth of per-vertex values, saved in “curvature” format. Because the template data is sampled to a particular surface mesh, this conjures the idea of “painting to a surface”.
Examples¶
>>> from nipype.interfaces.freesurfer import Paint
>>> paint = Paint()
>>> paint.inputs.in_surf = 'lh.pial'
>>> paint.inputs.template = 'aseg.mgz'
>>> paint.inputs.averages = 5
>>> paint.inputs.out_file = 'lh.avg_curv'
>>> paint.cmdline
'mrisp_paint -a 5 aseg.mgz lh.pial lh.avg_curv'
Inputs:

be sampled or 'painted'

args: (a unicode string)
Additional parameters to the command

Average curvature patterns
flag: -a %d
environ: (a dictionary with keys which are a bytes or None or a value
of class 'str' and with values which are a bytes or None or a value
of class 'str', nipype default value: {})
Environment variables
out_file: (a file name)
File containing a surface-worth of per-vertex values, saved in
'curvature' format.

Outputs:
out_file: (a file name)

'curvature' format.
