Sensor fusion and raw data

Hi everyone,

I have been using the MetamotionR sensor for clinical motion analysis. I have no programming background, but recently got to grips with Matlab to process the data offline.

Can anyone explain to me how I can retrieve the output from the sensor fusion (euler or quaternion) module and simultaneously obtain the raw accelerometer/gyroscope/mag data.

Any advice would be much appreciated!

    There is no straight forward way to do it and streaming both the fused and raw data is not recommeded by us.

    Your options here are:

    1. Log all output
    2. Stream one, log the other
    3. Stream all but at reduced frequencies

    Thank you for your response Eric.

    Unfortunately I cannot see how any of these options would work as when I select euler angles or quaternions, accelerometer/gyro/mag are automatically removed from my list of sensor modalities. This also happens the opposite way round - if I select acc, gyro or mag - euler and quaternions are removed.

    This happens in stream or log mode with my device (metabase app on iphone).

    Is there another platform I should be using to collect the data?

    Thanks again for your support.

    No, this is the intended behavior of MetaBase and our recommended way of using sensor fusion.
