xyz2rch.hs
Usage: ./xyz2rch.exe <pathToQHUll> <file.xyz>
 
Haskell Script to convert a file of xyz coordinates to Recursive convex hulls 

Requires QHull to be installed: http://www.qhull.org/
Compile using Glasgow Haskell Compiler: http://www.haskell.org/ghc/
 	ghc -o xyz2rch.exe --make xyz2rch.hs

Input is a comma separated file.
Each line consists of the residue label and the x,y,z coordinates:

R,5.009,32.3,50.934
T,4.452,31.426,46.229
D,2.951,36.717,47.185
C,8.597,37.815,46.045
Y,7.599,38.124,41.282
G,2.986,39.221,41.892
N,-1.372,37.625,42.536
V,-0.51,34.194,38.027
N,-5.453,35.209,40.525
R,-4.096,40.343,40.107

Usage: ./xyz2rch.exe <pathToQHUll> <file.xyz>
