Once called on a list of instances, the instances can be concatenated as they will have the same list of bad channels. Parameters ---------- insts : list The list of instances (Evoked, Epochs or Raw) to consider for interpolation. Each instance should have marked channels. interp_thresh : float A float between 0 and 1 (default) that specifies the fraction of time a channel should be good to be eventually interpolated for certain instances. For example if 0.5, a channel which is good at least half of the time will be interpolated in the instances where it is marked as bad. If 1 then channels will never be interpolated and if 0 all bad channels will be systematically interpolated. copy : bool If True then the returned instances will be copies. Returns ------- insts_bads : list The list of instances, with the same channel(s) marked as bad in all of them, possibly with some formerly bad channels interpolated. rz-interp_thresh must be between 0 and 1, got %scSsg|]}|jdqS)badsinfo.0instr\/var/www/html/bwave/python/venv/lib/python3.8/site-packages/mne/preprocessing/interpolate.py 0sz!equalize_bads..cSsg|]}t|t|jqSrlentimesrrrrr3scSsg|]}t|jqSrrrrrrr5sc3s(|] \}}|jdkr|VqdS)rNr)rkr)ch_name durationsrr 9sz equalize_bads..cs g|]\}}|kr|qSrr)rrch) good_times interp_threshrrr>s cSsg|] }|qSr)copyrrrrrAsr)exclude) ValueErrorlistsetr from_iterable isinstancerappendsum enumeratenprrinterpolate_bads)Zinstsr"r#Zall_badsZ bads_keeprr)rrr!r"r equalize_badss2  r/cCs6t|tttf|}|dkr(td|}|ddkrNtd|d|d}|jd}t |jd<t }t }| }|D]b\} } |j | } |j | } || | g}t|| } t|| }t| |d}t| d | d g|jd d }||d dddd<t|trNt|| | d|| | dd||jd}nt|trt|dd| | df|dd| | dfd||jd}n8t|| | d|| | dd||j|j|jd}||| d | d <q|jt |ddt ||jd<||t |||jd<|S)a)Interpolate bridged electrode pairs. Because bridged electrodes contain brain signal, it's just that the signal is spatially smeared between the two electrodes, we can make a virtual channel midway between the bridged pairs and use that to aid in interpolation rather than completely discarding the data from the two channels. Parameters ---------- inst : instance of Epochs, Evoked, or Raw The data object with channels that are to be interpolated. bridged_idx : list of tuple The indices of channels marked as bridged with each bridged pair stored as a tuple. Returns ------- inst : instance of Epochs, Evoked, or Raw The modified data object.
