With the release of Sift v2025.07.23, HAS-Motion introduces Jiku, an Australian software startup company with big dreams, as our newest data analysis partner. Jiku released their first software product, called Power1D, in April 2025.
This new application supports experimental sample size planning and post hoc power analysis for one-dimensional waveform data. Researchers commonly collect this kind of data in biomechanics and analyse it with techniques like one-dimensional statistical parametric mapping. HAS-Motion and Jiku have worked collaboratively over the past 6 months and are pleased to announce that Power1D integration is now available to Sift users.
Powering Waveform Analysis
Several common software packages, like SPSS and G*Power, support statistical power analysis, but only for simple point-process data. Only Jiku’s Power1D supports power analysis for one-dimensional data including time series data like joint angle and force trajectories. Power1D supports drag-and-drop automated power analysis of existing datasets, and it also supports one-dimensional effect size and geometry sculpting for flexible and systematic consideration of different signal possibilities.
Todd Pataky, Jiku’s CTO says:
I am thrilled to partner with HAS-Motion and their wonderful team of talented scientists and engineers. Jiku’s vision for the future of the biomechanics software landscape aligns perfectly with HAS-Motion’s mission to empower researchers with advanced, state-of-the art analysis tools. We are delighted to see Jiku’s first software product join the already solid and rapidly expanding data analysis ecosystem that HAS-Motion has lovingly crafted.
Powering Modern Biomechanics
As we’ve highlighted previously, there is a real value in evaluating the waveforms that we collect with motion capture systems. Point values or summary statistics potentially throw away information. Waveform analysis allows users to work directly with their signals to derive insights about human motion.
This integration is another tool in the toolbox for every Sift user. Sift already offers easy query mechanisms, time normalization, and exploration for waveform data. Now it is possible to reason about statistical power and effect sizes from this waveform data.
Richard Moulton, President at HAS-Motion:
Sift has been designed from the ground up to help users manage and analyse their biomechanical waveforms. It was great working with Jiku for this integration; I’m looking forward to seeing users run with these tools and build powerful experimental frameworks.
Looking Ahead
This integration between Sift and Power1D is simply the first step in the two companies’ partnership. With similar philosophies around biomechanical analysis and a desire to make potentially complicated analysis techniques widely available, HAS-Motion and Jiku are poised to support biomechanists on the cutting edge for years to come.
