.SECOND INPUT FILE: SUB002
[Enter name of second real 3-D volume.]
.RING WIDTH:1.
[Enter the shell thickness in reciprocal space sampling units.]
.SCALE FACTOR (LOWER,UPPER): 0.6,1.2
[Give the range of scale factors by which the second Fourier must be
multiplied for the comparison.]
.MISSING CONE/WEDGE ANGLE(C/W):c
[Use 'C' if you have a missing cone and w if you have a missing wedge.
.MAXIMUM TILT ANGLE:30
[Give the angle of maximum tilt angle in degrees. (When the missing
cone is covered angle=90.0)]
.FACTOR FOR NOISE COMPARISON: 3.0
[The factor given here determines the FSCCRIT. Here 3.0 corresponds to
the 3 sigma criterion i.e., 3/SQRT(N), where N is number of voxels for
a given shell. You could use 2, 1,4 or anything.]
.DOCUMENT FILE: DOC001
[Enter name of doc file in which results are to be saved.]
NOTES
a) PHASE RESIDUAL = SQRT(SUM[(ABS(F1)+ABS(F2))*DPHI**2]/ SUM(ABS(F1)+ABS(F2))) where DPHI = The phase difference between corresponding Fourier, coefficients which should be < 45 DEG. b) SHELL CORRELATION = [SUM(F1*CONJ(F2))]/ [SQRT{SUM(ABS(F1)**2)*SUM(ABS(F2)**2)}] where CONJ implies complex conjugate.
