.FILE NUMBERS OR SELECTION DOC. FILE NAME: SELECTREF
[Enter numbers of reference files. The file numbers can also
be read from a selection document file where file numbers are contained in the
first register (not the keys).]
.REAL SPACE MASK RADIUS FOR EXP. AND REF. IMAGES: 25,15
[The radii applied in real space to the input and
reference images, respectively.]
.RADIUS OF ACF, MAXIMUM SHIFT: 20,5
[Enter the maximum radius of the self-correlation function to be used
in angle determination and the maximum shift to be considered.]
.CHECK MIRRORED POSITIONS? (Y/N) : Y
[Check mirrored image when using 1/2 coverage of
projection space.]
.TEMPLATE FOR IMAGE SERIES TO BE ALIGNED: DAT***
[Give the template name of the existing file series of
experimental images. These images will be checked for
alignment versus the reference images.]
.FILE NUMBERS OR SELECTION DOC. FILE NAME: 1-21
[Enter numbers of experimental files. The file numbers can also
be read from a selection document file where file numbers are contained in the
first register (not the keys).]
.DOCUMENT FILE NAME: PARM101
[This is the only output produced by this program.
It contains 6 columns:
1. Number of the most similar reference projection.
When this number is negative, the most similar is the
mirrored projection.
2. Not-normalized correlation coefficient.
Can be used as a similarity measure.
3. Angle.
In-plane rotation angle determined.
4. X-shift.
X translation determined.
5. Y-shift.
Y translation determined.
6. Experimental projection number.]
