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 data to be used | whole file |
-x# | number of lines to be ignored | 0 |
-c# | columns to be read | 1 |
-m#,# | no. of input columns,embedding dimension | 2,1 |
-d# | delay | 1 |
-W# | 0: Just write the eigenvalues 1: Write the eigenvectors. The columns of the output matrix are the eigenvectors. 2: Transformation of the time series onto the eigenvector basis. The number of components printed is determined by the -q flag. 3: Project the time series onto the first -q eigenvectors (global noise reduction). | 0 |
-q# | depending on -W: -W2: Number of components written -W3: Projection dimension | full dimension |
-o[#] | output file name | -o without argument means 'datafile'.pca (or stdin.pca if data were read from stdin) without -o means stdout |
-V# | verbosity level 0: only panic messages 1: add input/output messages | 1 |
-h | show these options | none |
