4.75 sddsshift

• description:
  sddsshift shifts the given data columns by rows.
• examples:

  sddsshift <inputfile> <outputfile> -columns=Values -shift=5 -zero

• synopsis:

  sddsshift [inputfile] [outputfile] [-pipe=[input][,output]]
   -columns=inputcol[,...]
   [-zero]
   [-shift=points | -match=matchcol]
   [-majorOrder=row|column]

• files: The output file contains all the columns from the input file as well as new columns named Shiftedinputcol and new parameters named inputcolShift. Exposed end-points are set to zero if the zero option is provided, otherwise they are set to the value from the first or last row as appropriate.
• switches:
  • -pipe=[input][,output] — Standard SDDS pipe options for reading/writing files from stdin/stdout.
  • -columns=inputcol[,...] — The names of the columns to be shifted.
  • -zero — Set exposed end-points to zero.
  • -shift=points — Number of rows to shift columns. Positive and negative numbers are both allowed.
  • -match=matchcol — The columns are shifted to minimize the least squares error relative to matchcol.
  • -majorOrder=row|column — Specifies the binary SDDS layout.
