**************************VARIABLES***************************************
* {i}, {j}, {m}, {n}, and {M} macros must be specified at the command line
* {i} and {j} are the two C13 spins (in the extended molecule)
* {m} is the number of protons to use in the spin system
* {M} is the number of protons in the extended molecule (ggv.cor file)
* {n} is the number of the non-proton nuclei in the extended molecule
**************************************************************************
N=2+{m}   // the total number of spins in the spin system

* Each ({i},{j}) 13C pair has its own nearest environment of protons
* In the files c{i}c{j}h{M}.s2e all protons in the extended molecule are
* sorted according to their closeness to the ({i},{j}) pair of carbons.
* The line below selects N nearest protons from the extended molecule
