"Nireports is a framework to easily combine what we call reportlets, that is data visualizations that help assess the quality of a particular processing step, into HTML visual report. In this notebook, we give you an example about how to build your own visual report using the nireports framework. The goal with this example visual report is to summarize some group properties of functional connectivity (FC) matrices computed from a single dataset in order to assess the quality of connectivity extraction.\n" | ||

"A reportlet does not have to be stored in an image format, it is also possible to incorporate HTML chunks into the overall report. Let us look at an example together. The goal with the next reportlet is to verify whether each session has enough timepoints after censoring to reliably estimate FC. If not, that session needs to be identified and excluded. We use plotly to generate an interactive plot in which hovering on the points tells you the session it corresponds to. The interactivity would not be possible with an image that is why we store the reportlet in HTML format." | ||
