Defragments data in a .tdms file.
Use this node to clean up your .tdms data when it becomes cluttered and to increase performance. Data becomes cluttered when you rewrite unnecessary metadata. See TDMS Segments and Metadata on the Details tab for more information.

Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error

Every time a node appends data to a .tdms file, the file creates a new segment. A segment consists of the following three parts:
When you set properties on TDMS nodes, you can omit meta information that is identical from one segment to the next, like channel names and properties. This is optional, but omitting redundant meta information significantly speeds up reading the file and reduces the binary footprint.
If you choose to write redundant information, you can later remove it using the TDMS Defragment node.
Where This Node Can Run:
