DIV - Divide real or complex files

(11/01/12)

PURPOSE

Divides an image, volume, Fourier transform by one or more divisor images and places result in an output file. All inputs must have same dimensions.   Example.

SEE ALSO

DIV 2 [Pairwise divide series of real or complex images]
MUL [Multiply two or more, real or complex images]

USAGE

.OPERATION: DIV

.INPUT FILE: PIC001
[Enter the name of the first file to be divided. (Header positions from this file are transferred to output.)]

.DIVISOR FILE: PIC002
[Enter the name of file containing divisor. Can be same as first file.]

.OUTPUT FILE: PIC999
[Enter the name of file for output. Can be the same file as either input.]

SPIDER will ask:

.DIVISOR FILE: *
[Enter '*' if no more files are to be processed.]

NOTES

  1. If multiple divisor files (e.g. PIC001, PIC002, PIC003...) are used the final output corresponds to: PIC999 = PIC001 / PIC002 / PIC003 ...

  2. This operation is the same as the obsolete 'MU D' which is kept for legacy compatibility.
