MetaPath is now Pathomx 04.02.2014
MetaPath has now been renamed Pathomx. The name change was neccessary due to a name clash with another piece of published bioinformatics software, but it also better reflects the focus on analysis of multi-omics data in a pathway context.
Transmit extra data with signals in PyQt 13.01.2014
Signals are a neat feature of Qt that allow message-passing between different areas of your program. To use a signal you attach a function to be called in the event of the signal firing, usually accepting a small item of data about the signal state. However, there is a limitation: the signal can only emit the data it was designed to do. So for example, a QAction has a .triggered that fires when that particular action has been activated. Unfortunately the receiving connected function only receives one thing: checked=True or False. In other words, the receiving function has no way of knowing which action triggered it. This is usually fine. You can tie a particular action to a particular function. However, sometimes you want to trigger multiple actions off the same type of action, and treat them differently. Here’s a neat trick to do just that.
MetaPath v2.0.0 has been released today! This latest version features a new visual editor for construction fo analysis workflows, new analysis plugins, graphing powered by Matplotlib and all sorts of other goodness. Downloads are available for Windows and MacOS X.
It’s been a while since I’ve posted an update on MetaPath development, which is finally forming into a solid package ready for publication. The latest version is available here on Github, with binary packages to follow in the near future. It’s quite a transformation from earlier versions, so I thougth I’d take some time to walk through the new features and ideas, with a few notes on implementation.
