@CaroAMN @inemesb I've resolved all the issues, added testings for all optional inputs, and closed the unnecessary PR on nf-core/test-datasets ! Thank you so much for helping me. This is my first solo on making a module, and I've learned a lot.

There are two suggestion from @inemesb that are still open ( for emitting the version ), otherwise it looks good to me.

Thank you for your great work @chaochaowong, its looking very good! Some tiny nitpicks plus those version emits to consider and you should be all good:)

@inemesb How did you find those nitpicks??? Is there a tool I can use to catch those tiny mistakes next time? Thank you very much. Moreover, I saw you were involved in merging the test datasets for pb-cpg-tools. Are you guying writing the module? I am looking forward to including it to the nf-core/pacvar pipeline once it becomes available. This hificnv is for the pacvar pipeline as well.
