Hand painted hemispheric lesion mask seems not used by the pipeline

Hello all,

I would like to use the hemispheric lesion mask to make fMRIPrep just process the left healthy hemisphere, and just normalize the left hemisphere to the template, but it seems the pipeline still detected brain mask and brain tissue by its own way.

So if someone has a good idea how to deal with the issue, please let me know !

Thanks for your time,
