Summary
[edit]

The Shuffle CHOP reorganizes the samples in a set of channels.

It is useful for transforming data received by the SOP to CHOP and TOP to CHOPs into channels containing only one row or column. Data can be easily manipulated, then transformed back if needed.

Parameters - Shuffle Page

Method method - - Chooses the operation "shuffle" performs:

  • Off off -
  • Swap Channels and Samples swap - Performs a channel transpose operation, by storing all samples at the same index in the same channel. If 25 channels are in the CHOP with a length of 33 samples, 33 channels will be created with a length of 25.
  • Sequence Channels by Name seqname - Sequence channels together that share the same alphabetic name, in the order of their number. (i.e. chan2, chan3 and chan1 would be sequenced in the order chan1, chan2, chan3).
  • Sequence All Channels seqall - Sequence all channels in the CHOP resulting in one long channel.
  • Sequence N Channels seqn - Sequence channels in groups of N together. For N=4, channels 0 to 3, 4 to 7, etc. will be sequenced.
  • Sequence Every Nth Channel seqeveryn - Sequence every Nth channel together. For N=4, channels 0,4,8,.., 1,5,9,..., etc. will be sequenced.
  • Sequence All Samples sallsamples -
  • Split All Samples splitall - Split every channel into channels of 1 sample, each containing a different sample from the original channel.
  • Split N Samples splitn - Split each channel into segments of N samples (specified below).
  • Split Every Nth Sample spliteveryn - Take every Nth sample from the original to form N new channels.

For all splitting operations, channels will be numbered according to their segment number. (i.e. chan would be split into chan1, chan2, chan3, etc).

N Value nval - The value of N for Sequence: Every Nth Channel, Sequence N Channels, Split N Samples and Split Every Nth Sample.

Use First Sample Only firstsample - Just use the first sample of each channel.


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).
