Hi R. Matt, I forwarded this message to Donald McLaren, but haven't heard from him.
Meanwhile, I found this excerpt from an email from Donald to David Van Essen on January, 11, 2010: > The transform between the 112RM-SL and D99 is non-existent because we > took our 112RM average atlas and aligned it to the D99 brain to create > the 112RM-SL atlas. I have enclosed the final_ave_reg.mat (the > transform) and final_ave_reg.mat.prm (the breakdown of the rotation, > scale, translation, and skew parameters). This will be the closest > transform to the 112RM-SL to F99 that we have.
