The Reorder CHOP re-orders the first input CHOP's channels by numeric or alphabetic patterns. Either a channel pattern specifies the new order, or a number sequence specifies the new order.
If the second input, the Order Reference is present, the Numeric Pattern and Character Pattern are ignored, and the first input CHOP's channels are reordered to match as well as possible the reference CHOP's. In this case, Method is not used.
Channel values are never affected.
Parameters - Reorder Page
method - ⊞ - There are three different reordering methods. You can enter a Numeric Pattern, a Character Pattern, or use an optional second input CHOP as an order reference.
- Numeric Pattern
numeric- This reorders the channels by channel number.
- Character Pattern
character- This reorders the channels by channel name.
- Base Name Sort
basename- This reorders the channels by their base name discounting the numeric suffix. For example
chan1, abc10will be reordered to
- Numeric Suffix Sort
numsuffix- This reorders the channels by their numeric suffix discounting the base name. For example
abc10, chan1will be reordered to
- Channel Value Up
chanvalueup- This reorders the channels by the channel's value, lowest first.
- Channel Value Down
chanvaluedown- This reorders the channels by the channel's value, highest first.
reverse- This reverses the input CHOP's channel order.
random- This reorders the channels randomly.
- Merge N Groups
group- This reorders the channels in groups the size of N, specified through the
N Valueparameter. This can be useful if you have a sequence of channels
r1, r2, ., rx, g1, g2, ., gx, b1, b2, ., bxand your desired order is
r1, g1, b1, r2, g2, b2, ., rx, gx, bx
- Every Nth Channel
split- This reorders the channels by selecting every Nth channel, specified through the
orderref - ⊞ - Only enabled if a second input is present.
- By Name
- By Index
numpattern - This reorders the channels by channel number. Normally the index order is 0,1,2,3... etc.. The first channel is at index 0. Standard numeric patterns are allowed such as
charpattern - This reorders the channels by channel name. Standard character patterns are allowed such as
"chan? ch*". See Scope and Channel Name Matching Options p. 102 in the section, Standard Options of CHOPs.
seed - Only available if
Channel Reorder Method is set to "Random", specify any number, integer or non-integer, which starts the random number generator. Each number gives completely different patterns, but with similar characteristics.
nvalue - Only available if
Channel Reorder Method is set to "Merge N Groups" or "Every Nth Channel".
rempos - ⊞ - Channels that do not match are called "remaining" and can also be ordered: they can be placed at the At Beginning or At Ending (in reference to the position of the matched channels).
- At Beginning
- At Ending
remorder - ⊞ - The channels that did not match can have the Same as Input order, or can be sorted AlphaNumerically.
- Same as Input
Parameters - Common Page
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 - 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.
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
autoexportroot - This path points to the root node where all of the paths that exporting by Channel Name is Path:Parameter are relative to.
exporttable - The DAT used to hold the export information when using the DAT Table Export Methods (See above).
- Input 0 -
- Input 1 -

A parameter in most CHOPs that restricts which channels of that CHOP will be affected. Normally all channels of a CHOP are affected by the operator.
A Time Slice is the time from the last cook frame to the current cook frame. In CHOPs it is the set of short channels that only contain the CHOP channels' samples between the last and the current cook frame.
samples-per-second of a CHOP. Each CHOP in your network has a sample rate, whether it is used or not. The overall timeline has a "frame rate", which is the number of animation frames per second, generally your monitor display frequency.
Exporting is the connection of CHOP channels to parameters of operators. The output of each exporting CHOP is one or more channels, active only while the CHOP Viewer is on. The current value of a channel can be exported to a parameter of any operator, overriding that parameter's value. See Parameter.
Parameters in TouchDesigner are an operator's settings (numbers, menus, flags, strings, paths) which the user can alter. Parameters for any operator can be opened by right-clicking on the operator and selecting "Parameters..." A currently selected operator's parameters can be viewed in a Network Editor by pressing the keyboard shortcut 'p'.
