FrameTree: mapping data trees onto frames

In this presentation, Dr. Tom Close presents FrameTree, a Python framework that is used to map categorical data organised into trees onto virtual "data frames" for analysis. Imaging data is typically stored within tree-structured data repositories, such as the XNAT platform used by the Australian Imaging Service. This structure reflects how the data is acquired and classified by projects, subjects, visits, etc… However, for the datasets to be statistically analysed, the data need to be arranged within data frames. Frametree provides a framework perform this mapping by overlaying virtual rows and columns onto the trees the data are stored in, thereby facilitating analysis of the imaging data in place.
