Default SnappyHexMesh on multi-STL geometry in foam extend

Hello friends,

Previously I used OpenFOAM3.0+ to generate a mesh based on 12 separate STL files (the different surfaces that define my patches). In OF30+, the procedure is quite straightforward:

blockMesh (container box for the STL geometry)
surfaceFeatureExtractDict (extract surface features from STL files)
snappyHexMesh (generate a mesh with patches)
The problem is that I now need to switch to foam-extend, and the same procedure does not apply. The surfaceFeatureExtract requires to specify a surface and an "output set", according to the following error I get:

Usage: surfaceFeatureExtract <surface> <output set> [-DebugSwitches key1=val1,key2=val2,...] [-DimensionedConstants key1=val1,key2=val2,...] [-InfoSwitches key1=val1,key2=val2,...] [-OptimisationSwitches key1=val1,key2=val2,...] [-Tolerances key1=val1,key2=val2,...] [-case dir] [-deleteBox ((x0 y0 z0)(x1 y1 z1))] [-dumpControlSwitches] [-includedAngle included angle [0..180]] [-minElem number of edges in feature] [-minLen cumulative length of feature] [-noFunctionObjects] [-set input feature set] [-subsetBox ((x0 y0 z0)(x1 y1 z1))] [-help] [-doc] [-srcDoc]

Wrong number of arguments, expected 2 found 0

FOAM exiting
If any of you guys ever used foam-extend for such purposes, could you please explain to me what this "output set" is?

Any help would be deeply appreciated, thanks for your time guys,
