[EMBOSS] newcpgreport

[Staffa, Nick (NIH/NIEHS)]

I have been using EMBOSS newcpgreport by

says:
By default, this program defines a CpG island as a region where, over an
average of 10 windows, the calculated % composition is over 50% and the
calculated Obs/Exp ratio is over 0.6 and the conditions hold for a minimum
of 200 bases. These conditions can be modified by setting the values of the
appropriate parameters.

I may be very dull and unimaginative, but I'd sure like a more detailed
explanation of what the program is doing to define a CpG island.
Does anyone know where this might be found?
Or even the code.

Can anyone help please.

Thanks
