Phase -- Create a phase map
usage:-phase out max thrsh ptyp np dp p2 wrap
Generate phase maps when used with -correlate, -movie, or -fft flags. Its arguments are:
- max - maximum phase value; default is NPHASE
- thrsh - threshold correl. (or power) value; must be above this to see phase
- ptyp - pixel type for phase map (OUT); default is 2 (float)
- np - number of phase steps; default is num. steps in 1 reference cycle
- dp - phase step size; default is 1
- p2 - phase 2 flag; provides access to phase values other than maximum, as:
- 1 - replace correl. val. with max correl minus correl 180 deg out of phase
- 2 - replace correl. val. with correl value 180 degs out of phase
- filename - create output file with correl. coeffs. at all phase offsets
- wrap - cross correlation flag for whether to wrap reference vector around to the beginning if shifting puts it past the end of the data
Default is 1 (yes) if the ref has repeated cycles, else 0 (no)
