This task will convert phase probabilities between the two common forms: Hendrickson-Lattman coefficients, and phase and figure-of-merit. Note that you should never do this, except to generate phases for export. CCP4i2 will convert phases internally as and when required. Converting to phase and figure-of-merit loses information.
The input to the task is a set of phases. If the phases are in the form of Hendrickson-Lattman coefficients, they will be converted to phase and figure-of-merit. If they are in the form of phase and figure-of-merit, they will be converted to Hendrickson-Lattman coefficients.
