Firstly, thanks everyone for asking questions and providing answers. I am new to the fMRI, and this is my first time asking a question in this forum. Please excuse the wording of my questions. Would you like to provide information about the following questions?
My questions are about @auto_tlrc command. In the past, default -pad_base was 40. Recently, the default -pad_base is 15 (Version AFNI_19.3.16 ‘Nero’).
a) What is the purpose of pad_base?
b) What was the reason that the default pad_base was changed?
c) What is the impact using big or small pad_base input?
d) What are the pros-cons of using bigger pad_base?
Thanks and have a nice day
