<p dir="ltr">There is a python function "get_chpi_positions" that will take a raw instance with those quaternion values stored (i.e., processed by maxfilter) and convert them to translation and rotation parameters for you. If you want to write some visualization tool in top of it, it would be much appreciated! If so, please open an issue and we will discuss it further. </p>
<p dir="ltr">We also have a work in progress to estimate the positions from the chpi signals themselves (i.e., raw data not processed by maxfilter), but that isn't working properly yet. </p>

The data is actually added to the fif file. I would recommend opening<br>
an issue on github, and let the discussion grow there. I believe you<br>
should already be able to with just the raw plotter in python (as at<br>
least the q values are stored as channels in the fif file). There is a<br>
lot of activity at the moment around maxfilter related issues.<br>
