AD - ADd images

(8/1/97)

PURPOSE

Adds two or more pictures or volumes together. The sum is placed in an output file.

SEE ALSO

AD M [Add images - with a multiplier]
AS R [Average images - find & save variance, better]
PA [Patch an image into another image]

USAGE

.OPERATION: AD

.INPUT FILE: PIC001
[Enter the name of the first file to be added.]

.NEXT INPUT FILE: PIC002
[Enter the name of the next file to be added. Can be same as first input file.]

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

The system continues:

.NEXT INPUT FILE: PIC003
[Enter the name of the third file to be added.]

'AD' will continue in this manner until an asterisk ('*') is given as the name of the next input file.

NOTES

  1. 'AD' only works for files with the same dimensions. To add files of different dimensions, use PATCH (see 'PA').

  2. For adding an entire file series, is is more practical to use operation 'AS R'. This will also produce a variance map.
