• name:
  peakfind
• synopsis:

  peakfind inputfile [ outputfile] [-threshold= level] [-smooth= integer] [-absolute_value]

• description:
  peakfind finds peaks in a data set, with optional smoothing and a user-defined threshold. A peak is defined as any point that is higher than its two nearest neighbors.
• files:
  inputfile is the file containing the data set to analyse for peaks; the data is assumed to be ordered by increasing abscissae. outputfile is the optional file to which the location and value of any peaks will be written; if omitted, the data is written to the screen.
• options:

  threshold

  
  Requests that peakfind ignore peaks of value less than threshold. By default, all peaks are considered valid.

  smooth

  
  Requests smoothing of the data by averaging repeatedly over groups of three consecutive points. The integer is the number of repetitions of the averaging.

  absolute_value

  
  Requests that the absolute value of the ordinates be taken prior to peakfinding.
