Dear SPM experts,
I included six parameters in the parametric modulations. However, the result indicated that one parameter (i.e., maxChunkSize) was not unique. I don't understand why this could be a problem because the parameters in the parametric modulations were covariates to my experimental conditions. They were not supposed to be unique.
I attached the script for the first level analysis and the resulting design matrix. I appreciate that someone could point out to me what is wrong. Thanks!
Sincerely,
Veda
