Dear SPMers,
I’m using a matlab script to generate mat-files for the 1st level “load multiple conditions” option. This script generates a mat file with three columns: name / onset / duration. Now I want to include a parametric modulator in the 1st level analysis. Which columns do I have to include additionally in the mat-file, so that spm automatically generates a 1st order polynominal expansion in the 1st level design matrix?
Thanks in advance and kind regards,
Ben
