The data pipe is simply created by the command
[firstnumber=3] # Create the 'rx' data pipe. pipe.create('rx', 'relax_fit')
This user function will then create a relaxation exponential curve-fitting specific data pipe labelled ``rx''. The second argument sets the pipe type to that of the relaxation curve-fitting. Setting the pipe type is important so that the program knows which user functions are compatible with the data pipe, for example in the steady-state NOE analysis the function minimise.execute (see page ) is meaningless as the NOE values are calculated directly rather than optimised.
