Which parameter in the function ants.build_template() in antspy corresponds to the -r option in buildtemplateparallel.sh

[angolin22]

hello, thanks for your work! I want to ask some questions:

1. Could I ask that which parameter in the function ants.build_template() in antspy corresponds to the-roption in buildtemplateparallel.sh
2. Does ants.build_template() support mask-based registration?
3. Does CT images of constructing the template require preprocessing, such as resampling to isotropy and normalizing the Hu value to 0-255? Thanks for your reply!
