USAGE

.OPERATION: CA SR

.CORAN/PCA FILE PREFIX: coran_t_
[Enter the prefix for the files created in 'CA S'.]

.ENTER FILE NUMBERS TO BE USED (e.g. 1-8,12-22,55): 1-80,90-95
[Numbers are consecutive, and refer to the sequence of files specified in 'CA S'. ]

If the source 'CA S' run utilized PCA, the following question will appear:

.SUBTRACT AVERAGE IN PCA RECONSTRUCTION? (N/Y): N

.ENTER FACTORS TO BE USED: 2-4
[Enter the factors to be used for image reconstitution. Note that the numbers have to be less that the number of images and less or equal to the number used in 'CA S'.]

.OUTPUT FILE TEMPLATE: SRI_****
[Enter the prefix for the files created here.]
