plot2 module <phase>
This module allows (approximate) phasing of the
(1-dimensional) slice which has been selected.
The data is real, and for phasing it must be complexified,
which is accomplished by a Hilbert Fourier transform.
NOTE: If the number of points in the slice is not
a power of 2 then the data is extended by zero in
order to achieve this, before use of the Hilbert
Fourier transform. This does not work perfectly,
but seems to work well enough for phasing purposes.
- {on : off} <phase_on_off>
-
This determines whether phasing is done to the slice.
The display is automatically updated, so this may be
used to toggle between a phased and unphased slice.
- {pivot} <phase_pivot>
-
The phase pivot. This must be specified in points.
The points are counted starting at 1.
- {phase 0} <phase0_value>
-
The 0 phase value. Lower and upper limits may be
specified. The value can be interactively changed.
The value and limits must be specified in degrees.
- {phase 1} <phase1_value>
-
The 1 phase value. Lower and upper limits may be
specified. The value can be interactively changed.
The value and limits must be specified in degrees.
- {apply} <apply>
-
Update the slice parameters and display the result.
- {dismiss}
-
Close the module (the parameters are remembered).
