USAGE

.OPERATION: CA SRP

.ENTER FILE TEMPLATE (EG. PIC****): TST***
[Enter the template for the file or file series to be created, doesn't have to be the same as original file series name.]

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

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

.COORDINATE FILE CODE: 2
[Enter the number identifying the three sequential files used to store the output from the previous 'CA_S' run: IMC#, PIX#, EIG#.]

.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'.]

[If there is no image with the above given number, then coordinates are solicited for each of the factors specified]

.ENTER COORDINATES FOR EACH FACTOR SELECTED: 0.0013, -0.0011,
0.0004

NOTES

  1. The purpose of this command is threefold:

  2. To reconstitute approximation of original images using chosen factors: use file numbers of the original images in "ENTER FILE NUMBERS";

  3. To create eigenimages - images corresponding to chosen eigenvectors: use file number (one) non-existing in the original image series in "ENTER FILE NUMBERS", answer Yes in "SUBTRACT AVERAGE IN PCA RECONSTRUCTION", use only one (chosen) factor number in "ENTER FACTORS TO BE USED", and unswer 1.0 in "ENTER COORDINATES FOR EACH FACTOR SELECTED" (or -1.0, since the sign of eigenvector is not determined by the analysis);

  4. To create non-existing images using chosen factors and arbitrary coordinates: use file numbers non-existing in the original image series in "ENTER FILE NUMBERS", answer No in "SUBTRACT AVERAGE IN PCA RECONSTRUCTION", enter (arbitrary) factor coordinates in "ENTER COORDINATES FOR EACH FACTOR SELECTED".
