If you know how to calculate a correlation coefficient from first principles
you'll find that
what the paper does is the following :
Take two 37-marker haplotypes.
Calculate the correlation coefficient using excel, but pretend that instead
of 2 people with 37 attributes, you have 37 people with 2 attributes.
Take the reciprocal of the 'correlation coeficient' so calculated.
Subtract 1.
Multiply by 10,000.
That's the RCC.

I used the MS Excel 2010 Correlation Coeficient function.
RCC is 10000 *(1 - Correlation Coefficient)
