nmrglue.process.pipe_proc.fsh(dic, data, dir, pts, sw=True)

Frequency Shift

This function does not perfrom a Hilbert transfrom when data is complex, NMRPipe seems to. As such the results of the imaginary channel differs from NMRPipe. In addition MAX/MIN value are slightly different than those from NMRPipe.

Parameters:

• dic Dictionary of NMRPipe parameters.
• data array of spectral data.
• dir Direction of shift, ‘rs’ or ‘ls’.
• pts Number of points to shift.
• sw True to update chemical shift calibration parameters.
