Everything not being a valid option will be interpreted as a potential datafile name. Given no datafile at all, means read stdin. Also - means stdin
Possible options are:
| Option | Description | Default |
|---|---|---|
| -l# | number of points to use | whole file |
| -x# | number of lines to be ignored | 0 |
| -c# | column to be read | 1 |
| -m# | embedding dimension | 5 |
| -d# | delay for the embedding | 1 |
| -q# | dimension of the manifold to project to | 3 |
| -k# | minimal number of neighbours | 30 |
| -r# | minimal size of the neighbourhood | (interval of data)/1000 |
| -i# | number of iterations | 1 |
| -2 | use euclidean metric instead of the tricky one | tricky metric |
| -o# | output file name | without file name: 'datafile'.opt.n, where n is the iteration (or stdin.opt.n if data was read from stdin) without -o the last iteration is also written to stdout |
| -V# | verbosity level 0: only panic messages 1: add input/output messages 2: add average correction and trend 4: add how many points were corrected for which epsilon | 7 |
| -h | show these options | none |
