Wire-Cell Toolkit Auxiliary
(top)

This core WCT package enjoys a special position in the dependency tree. It depends on WireCellIface as do other “implementation” packages. But, unlike the others that do not have any compile time inter-dependencies, the other “implementation” packages may have compile time dependency on WireCellAux.

Some categories of code appropriate for aux:

• general purpose implementation of IData interfaces (eg the Simple* classes)
• INode implementations that provide general purpose data converters (eg, ITensorSet <--> IFrame)
• general utility code that operate on interfaces (eg, FrameTools)

• Support for noise modeling
• Tensor data model
• WCT frames as tensors
• frame files
• array representation of cluster graphs
• the “cluster shadow” concept
