Why do you take negative acceleration readingds?

qin1 = quatconj(initQuaternion(-s1(1,2:4), s1(1,8:10)));

Hi Marco,

in this main file, and also when you call the Magdwick function, you seem to negate the acceleration readings, i.e., -s1(1,2:4) rather than simply s1(1,2:4). Can you explain why would this be necessary?

Best regards,
