Hello Carmine,

-s <sigma> is a shortcut for the common operation of creating a gaussian kernel of <sigma> mm and applying mean filtering ( smoothing ). -roi takes pairs of voxel co-ordinates and zero all voxels outside of that rectangular ROI.

The FLIRT user guide:

https://fsl.fmrib.ox.ac.uk/fsl/fslwiki/flirt/UserGuide

covers a number of command line tools that convert between voxel and mm co-ordinates.

hope this helps,

Kind Regards,

Matthew

Dear all,
could someone give me more informations about the follows fslmaths option: -s <sigma>; -roi <xmin> <xsize> <ymin> <ysize> <zmin> <zsize> <tmin> <tsize> ?
Also there is a way to convert voxel coordinates in mm?
thank you
