.(T)RANSFER OR (W)EIGHTING-FCT.: w
[Enter if you want the Transfer function or the Weighting function
(= 1./(Transfer function)). The calculation of the transfer
function may be desirable for test purposes]
.CRITICAL VALUE FOR W: 0.6
[Give upper limit for inverse of weighting function (=transfer
function) to avoid noise enhancement. (remark: this parameter
will be changed. A value smaller than 1 allows a weighting
function larger than 1. A value of 0.6 seems to be adequate) ]
.3D VOLUME DIAMETER: 80
[Enter diameter of reconstructed volume in real space]
.GENER.ANGLES IN (L)ABEL,(D)OCF,(E)XTERNAL: L
[Enter if angles of the projections, which are used to generate
the weighting function are contained in the label of the files,
in a document file or if they will be entered externally. It is
strongly recommended to provide these angle in the file label.
This is the most used mode and thus the best tested.]
.WGT. ANGLES IN (L)ABEL,(D)OCF,(E)XTERNAL: L
[Enter if angles of the projections which will be weighted are
contained in label, document file, or externally given. s. remark
above.]
.TEMPLATE OF INPUT FILE SERIES: PRO***
[Enter prefix of input files]
.TEMPLATE OF OUTPUT FILE SERIES: PRW***
[Enter prefix of output files]
.FILE NUMBERS OF GENERATING FILES: 1,5,6-36
[Enter file numbers of the projections, which generate the
weighting function]
.FILE NUMBERS OF FILES TO BE WEIGHTED: 1,5, 7-36
[Enter file numbers of files which will be weighted]
If angles of generating projections are given externally:
.PHI: 10.
.THETA: 45.
[Enter phi and theta for each generating projection]
If angles of generating projections are contained in document file:
.DOC1: DOC001
[Enter name of document file which contains the angles of
the generating projections. see also note 2!!!]
.BOTH IMAGE SETS IDENTICAL (Y/N): N
[Answer "N"!. Only if the set of projections which generate the
weighting function and the set which is to be weighted are
identical you may answer Y.
Warning: Answer yes only, if both sets are really the same images,
corresponding to each other image by image including the file
numbers. N always works! ]
[Enter the angles of these projections]
