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 |
| -m# | number of columns to be used | 1 |
| -c# | column(s) to be read | 1 |
| -%# | noiselevel in percent | 5 |
| -r# | absolute noiselevel (or absolute variance if -g is set) | not set |
| -g | add gaussian noise instead of uniform | uniform |
| -I# | change the seed of the random number generator If # = 0, the seed is taken from the time command, which means the seed is set to the number of seconds since Jan 1st, 1970 | some fixed value |
| -0 | Don't read any data file, just generate random numbers with zero mean. (Requires -r and -l) | not set |
| -o# | output file name | -o without a name given: 'datafile'.noi (or stdin.noi if data were read from stdin) If no -o is given data are written to stdout |
| -V# | verbosity level 0: only panic messages 1: add input/output messages | 1 |
| -h | show these options | none |
