SPIDER: MUL O (Multiply with arithmetic OR)

MUL O - Multiply with arithmetic OR

(11/01/12)

PURPOSE: Combines two images of equal size according to 'OR' logic. As implemented the logic is as follows. Each output pixel is set equal to the value contained in the pixel from the 2nd input image. If the value from the second input image is zero, the output pixel is set to the value contained in the first input image. For legacy use this operation can be abbreviated to 'MU O'

SEE ALSO

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

USAGE

.OPERATION: MUL O

.INPUT FILE: PIC001
[Enter the name of the first image.]

.SECOND INPUT FILE: PIC002
[Enter the name of the second image. Can be same as first]

ARITHMETIC OR
.OUTPUT FILE: PIC999
[Enter the name of the output image. Can be same as either of the first two input files]

SPIDER will ask:

.SECOND INPUT FILE: *
[Enter '*' to terminate the operation.]

NOTES

This operations may only be used for images or volumes having the same dimensions.
