4.85 sddsregroup

• description: sddsregroup swaps the row indexing and page indexing of data in an SDDS file. That is, the i^th row of all data pages in the input file are collected and made into the i^th data page of the output file.
• examples: The file bpm.sdds contains the beam position monitor (BPM) readback as a function of time for a series of consecutive BPMs in a beamline. The defined columns are Time and x. The parameter is bpmIndex. The file is regrouped to produce data sets of x vs bpmIndex for each time value. The output is suitable to plot as a movie with sddsplot.

  • -warning — Report non-fatal warnings.
  • -verbose — Print processing information.
• files:
