Summary
[edit]

The Analyze CHOP looks at the values of all the values of a channel, and outputs a single-number result into the output. The output is one sample long. It can analyze for maximum, average, peaks and other aspects of a channel.

Parameters - Analyze Page

Function function - - This menu determines the function applied to the channel.

  • Average average - The average of the channel.
  • Maximum maximum - The maximum value of the channel.
  • Minimum minimum - The minimum value of the channel.
  • Index of Maximum maximumindex -
  • Index of Minimum minimumindex -
  • Sum sum - The sum of all the samples in the channel.
  • RMS Power rmspower - The RMS (root-mean-square) of the channel.
  • Value of First Peak firstpeakvalue - The value of the first peak in the channel.
  • Index of First Peak firstpeakindex - The index of the first peak in the channel. The index of the first sample is 0.
  • Value of Last Peak lastpeakvalue -
  • Index of Last Peak lastpeakindex -
  • Value of Highest Peak highestpeakvalue - The value of the highest peak in the channel.
  • Index of Highest Peak highestpeakindex - The index of the highest peak in the channel. If multiple samples have the same highest peak value, it returns the index of the last peak sample.
  • Value of Lowest Peak lowestpeakvalue - The value of the lowest peak in the channel.
  • Index of Lowest Peak lowestpeakindex - The index of the lowest peak in the channel. If multiple samples have the same lowest peak value, it returns the index of the last peak sample.
  • Total Peaks totalpeaks - The total number of peaks in the channel.

Allow Start Peaks allowstart - If the values of the first 2 samples are v0 and v1, if v0 > v1, count it as a peak. The default is to never count the first sample as a peak.

Allow End Peaks allowend - If the values of the last 2 samples are vn and vm, if vm > vn, count it as a peak. The default is to never count the last sample as a peak.

No Peak Value nopeakvalue - When no peaks are found, make this number (default is -1) the result that is output. When the Function is set to Peak Index or Peak Value, it is a way to detect that no peaks were found.

Analyze Valleys vs Peaks valleys - Analyze instead for the First Valley, Highest Valley, and Lowest Valley, when the corresponding Function menu options are chosen.


Parameters - Common Page

Time Slice timeslice - Turning this on forces the channels to be "Time Sliced". A Time Slice is the time between the last cook frame and the current cook frame.

Scope scope - To determine which channels get affected, some CHOPs use a Scope string on the Common page.

Sample Rate Match srselect - - Handle cases where multiple input CHOPs' sample rates are different. When Resampling occurs, the curves are interpolated according to the Interpolation Method Option, or "Linear" if the Interpolate Options are not available.

  • Resample At First Input's Rate first - Use rate of first input to resample others.
  • Resample At Maximum Rate max - Resample to the highest sample rate.
  • Resample At Minimum Rate min - Resample to the lowest sample rate.
  • Error If Rates Differ err - Doesn't accept conflicting sample rates.

Export Method exportmethod - - This will determine how to connect the CHOP channel to the parameter. Refer to the Export article for more information.

  • DAT Table by Index datindex - Uses the docked DAT table and references the channel via the index of the channel in the CHOP.
  • DAT Table by Name datname - Uses the docked DAT table and references the channel via the name of the channel in the CHOP.
  • Channel Name is Path:Parameter autoname - The channel is the full destination of where to export to, such has geo1/transform1:tx.

Export Root autoexportroot - This path points to the root node where all of the paths that exporting by Channel Name is Path:Parameter are relative to.

Export Table exporttable - The DAT used to hold the export information when using the DAT Table Export Methods (See above).
