Wire-Cell fans

Of course, everyone is a fan of Wire-Cell. This post isn't about you. It's about a common pattern that is found in Wire-Cell data flow graphs and how this pattern is realized at the WCT C++ level and how to form it in WCT configuration.

Out with cout and its an error to use cerr!

Overriding Configuration Parameters

Brett Viren — Wed, 15 Aug 2018 13:38:32 GMT

The WCT configuration language Jsonnet allows to exploit software development patterns such as "don't repeat yourself" (DRY) and object inheritance. They are exploited to factor a configuration into layers so that it may, in total, serve many uses. This post describes how to override a parameter from a base object.

Default Config Dumper

Brett Viren — Thu, 05 Jul 2018 13:15:44 GMT

WCT is very configurable. It provides a way for the expert that wrote the C++ component to provide sane defaults and a way that a user may override or augment those defaults. WCT helps such intrepid users to discover the defaults with the ConfigDumper WCT app component.

Response Refactoring

Brett Viren — Tue, 03 Jul 2018 22:59:30 GMT

In WCT we try to follow the mantra "everything is a component". One corollary to that is we try to avoid hard-wiring dependencies by having functionality accessed by hard-wired construction of concrete classes. The various classes having to do with responses suffered from not being available as components. This led to the entire toolkit having hard-wired behavior which hampers support for multiple detectors. This post describes some recent steps to fix this problem.

Pgrapher Configuration Improvements

A powerful new idiom has been developed to simplify developing Jsonnet configuration files for Wire-Cell toolkit's Pgrapher app component.

Signal processing now in component form

Brett Viren — Mon, 10 Jul 2017 22:16:43 GMT

Following in the footsteps of the recently announced porting of its functionality from the prototype to the toolkit the signal processing, is now usable in the form of WCT components. This is important as it paves the way to embedding the signal processing in other applications or frameworks, notably LArSoft.

New Configuration Data Package

Brett Viren — Fri, 23 Jun 2017 19:18:19 GMT

Today a new package joins the WCT family.

https://github.com/WireCell/wire-cell-data

This collects the "configuration data" files which are needed for input to WCT. These are generally compressed JSON files which have been converted to a WCT standard format from a variety of sources. The data includes wire geometry, field response, noise spectra and a couple initial deposition files.

Having this repository makes it easier for users to prepare to run WCT. At some point in the future this package may be installed along with the code, but for now, users need to clone this repo. For WCT to locate these files the produced directory needs to be added to the user's WIRECELL_PATH environment variable.

See the README file for details including a summary of the files available and commands to remake these files from their upstream sources.

Previously this data was kept online in a directory dump. That's still there for now. It includes some files not added to GitHub. In particular the "upstream" data from which the JSON files are converted (eg, the Garfield output) can be found. And next door to that directory is a plot dump directory which contains some diagnostic plots related to the conversion of these files which may be useful for experts to browse.

Jsonnet now mandatory and CLI parameter injection

Jsonnet is now a required external dependency.
