PO | [Convert image to polar representation - rays along Y.] |
RO I | [Rotational average - 2D Image output] |
RO SD | [Rotational average - single line output, doc file] |
.OUTPUT FILE: POL001
[Enter name of the file which will contain polar coordinate
representation of the input image.
The length of each line will be the minimal radius of the image from
the SPIDER center pixel. The height of the image will be
radius * 2 * PI. The first pixel originates from the
origin (center pixel) of a horizontal line halfway
down the image and following rows are extracted in a clockwise
direction.
Each line is NOT multiplied (weighted) by the square root of its radius thus the format of output differs from 'PO'. ]
.FULL OR HALF CIRCLE (F/H): F
['F' - convert whole circles;
'H' - convert only half of each circle.
Option 'H' is appropriate when autocorrelation images or
spectra from 'CTF FIND' are converted to polar representation.]
