.HELICAL REPEAT: 357.5
[Enter the helical repeat in A]
.GRID INTERVAL: 5
[Enter grid interval in A]
.MAP RANGE (FROM, TO): -150,150
[Give cubic volume boundaries. Must be multiples of
grid interval]
.TURN MAP UPSIDE DOWN (y/N): N
[Answer 'y' if you wish the map to be turned, <CR> or 'N'
if you don't]
.PHI ROTATION: 25.
[PHI rotation offset in degrees]
.Z TRANSLATION: 0.
[Z translation offset]
.RADIAL CUTOFF: 0.
[Terms with radius above cutoff are not computed. If
0 is entered, no cutoff is used.]
.B-FACTOR: 0.
[Optional Gaussian falloff parameter. If 0 is entered,
no falloff is applied.]
