Module: segmentation/freesurferseg

Performs Brain Tissues Segmentation using the FreeSurfer aparc and wmparc output files. Optionally, a binary mask of lesion can be add to correct the white matter mask.

Inputs

	Type	Description	Pattern
meta	map	Groovy Map containing sample information e.g. [ id:'test', single_end:false ]
