The output datatype of the App that detects bad channels is meg/fif-override (see https://brainlife.io/datatype/608195ce89df435fd26893c1), but as pointed out here Où stocker l'information "bad channels", MNE Python functions used the info stored in raw.info['bads'].

If raw.info['bads'] is not compliant with the info of channels.tsv, a warning is displayed to the user to tell him that, by default, only bad channels from channels.tsv are considered as bad: the info of his MEG file will be updated with those channels. The comparison between channels.tsv and raw.info['bads'] is performed at the beginning of each App.
