Set the CPMG pulse sequence information associated with a given spectrum.
spectrum_id: The spectrum ID string to associate the CPMG pulse sequence information to.
cpmg_frq: The frequency, in Hz, of the CPMG pulse train.
ncyc_even: A flag which if True means that the number of CPMG blocks must be even. This is pulse sequence dependant.
This allows all information about CPMG pulse sequence required for a relaxation dispersion analysis to be specified. This includes:
To identify the reference spectrum called `reference_spectrum', type:
[numbers=none] relax> relax_disp.cpmg_setup(spectrum_id='reference_spectrum', cpmg_frq=None)
To set a frequency of 200 Hz for the spectrum `200_Hz_spectrum', type:
[numbers=none] relax> relax_disp.cpmg_setup(spectrum_id='200_Hz_spectrum', cpmg_frq=200)
