4.108 sddsunwrap

• description: sddsunwrap looks for discontinuities larger than a threshold in a set of data. After each discontinuity it adds the appropriate multiple of the modulo to the data set.
• examples:
      sddsunwrap inputFile outputFile -columns=phase  
      

• synopsis:
      sddsunwrap [-pipe=[input][,output]] inputFile outputFile  
        [-columns=columnName[,...]] [-threshold=value] [-modulo=value]  
      

• switches:
  • -pipe[=input][,output] — The standard SDDS Toolkit pipe option.
  • -threshold=\emph{value} — Specifies the discontinuity threshold used to identify a wrap in the data, default is PI.
  • -modulo=\emph{value} — Specifies the value used to unwrap the data, default is 2*PI.
  • -columns=\emph{columnName}[,\emph{columnName}...] — Specifies the names of the columns to unwrap; wildcards are accepted. If not specified, all numerical columns in the input file are unwrapped. The output column is named as Unwrap<inputColumn>.
• files: The input file contains the column data to be unwrapped. The unwrapped data is saved into Unwrap<inputColumn> column in the output file.
