.COORDINATE FILE: IMC001
[Enter the name of the cluster file created by CORAN.]
.FACTOR NUMBERS: 1,3,4,6
[Enter the factors that you want to include in the
nonlinear mapping algorithm.]
.FACTOR WEIGHTS (2 PER LINE): 1,1.5
[Enter weights for each selected factor.]
.ASSIGN SYMBOLS (Y/N): Y
[enter Y if you want to have a map where symbols (letters)
are printed for specified images.]
.SYMBOL ASSIGNED TO IMAGE # FROM,TO: 1,100
[Enter the image numbers for which the symbol should be
used.]
.ASSIGN SYMBOLS (Y/N): .....
[This question reappears until you answer "N".]
.LOWER THRESHOLD FOR DISTANCES: 0.0001
[Images with a distance lower than this threshold are
considered identical and only one of a set of identical
images is used in the algorithm; the others are excluded,
enter 0 if you want to keep all elements.]
.DEFINE STARTING 2-D DISTRIBUTION:
[(1) GIVEN EIGENVECTOR PROJECTION
(2) RANDOM DISTRIBUTION
(3) EIDENVECTOR PROJECTION WITH MINIMAL STARTING ERROR.
(4) READ START DISTRIBUTION IN FILE COD001
.START:(1)GIVEN,(2)RANDOM,(3)MIN.ERR.,(4)READ: 1
[Enter the kind of start distribution you want.(will be changed !!!)]
.RELATIVE AXES OF START PROJECTIONS: 1,2
[If you entered '1' above for "GIVEN", the program asks
for the map you want to start with. The numbers entered
correspond to the position of the numbers entered for
"FACTOR NUMBERS". (Here the starting map will be factor 1
versus factor 3.)]
.NUMBER OF ITERATIONS: 40
[Give the number of iterations which should be done, if
the error never becomes less than epsilon. If in any
iteration step prior to the given one the error was less
than in the last iteration, the program continues until
the error is less than or equal to the smallest previous
error. However, there is an absolute limit of 200 iterations.]
.EPSILON: 0.001
[Enter the value of the remaining error when the iterations
should stop. This value may be 0. because the program has
additional controls to limit the number of iterations.]
.EXPONENT IN ERROR: 0.0001
[Enter the exponent, in the formula given above, of the
error. An exponent close to 1 means a stronger weight
for the small distances; a value close to 0, a higher
weight for the long distances. Normally in the first run
one should use an exponent << 1. Instead of 0 use a very
small value e.g. 0.00001, because the exponentiation in
VAX-Fortran sometimes does not tolerate an exact 0]
.2D FILE: COD001
[Document file in which the coordinates of the nonlinear map
will be stored. It can be used as input for another
nonlinear mapping process, or from a previous run. The file
is then overwritten with the new result. Also usable as input
to CA VIS (visual map)]
.MAP FILE: MAP001
[Enter the name of the file where the map will be displayed.]
.PAGES: 2
[Enter size of map: 1x1 or 2x2 pages.]
