Hi,

I would like to find out how I could use the cHPI data in the raw MEG file to pass into the head_pos parameter of Maxwell_filter() so as to perform movement compensation within MNE-Python. My MNE-Python version is 0.18.2.

I also have the Maxfilter applied data file (raw_tsss_mc.fif). But access to the Maxfilter is restricted temporarily and hence I am not able to generate the headpos file.

Thanks

Dear Nithya,

you need mne-python version >= 0.20 to use:
