Description of the program: makenoise


This program just takes the data and adds a desired amount of noise to it. It is largely redundant with addnoise but uses a better random number generator, Rainer believes. On the other hand, addnoise can be run as a noise source without any input file.

Usage:

makenoise [Options]

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
-%# 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
-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


Description of the Output:

The output consists of the noisy time series.
