Hi Estephan I actually don't know what the FSL masks correspond to. If they are volumetric labels then they are unlikley to perfectly correspond to anything in FreeSufer. If you really want correspondence you are probably best off taking their maps and mapping them to our surfaces. Note that

So in other words, there is not a tool in Freesurfer similar to mris_label_calc but that works with labels defined in the volume rather than on the surface, correct? I am simply double checking that there is not a simple single step tool before I write a matlab script or start transforming labe

'mris_calc' accepts as inputs volumes or "curvature" files. Calculations on labels don't make sense in the context for which "mris_calc" was written -- what would an operation like "label1 multiply-by label2" even mean? Having said that, 'mris_calc' does support labels in as much as using a la

Hi Salil, You should be able to apply an isosurface to each subfield label in freeview. You can set the color for each isosurface as well, since the default is gray. You need to be in the 3D view in order to display isosurfaces. -Louis On Thu, 6 Feb 2014, Salil Soman wrote: Hi, I generate
