Dear AFNI gurus,
We've been using retroTS.M to generate regressors fed into retroicor. We're looking for any form of documentation that will outline what these regressors are exactly. We tried deciphering the matlab code, but without much success. Is there any resource that documents this? From the bits & pieces we picked off the board it seems there's one regressor for RVT and possibly some reflecting the cardiac and respiration series (directly or indirectly), but we did not find much more.
Thanks,
Oori
