Dear SPMers,
I am using SPM2 to analyze fMRI data. The design file (.mat) was generated
by vectors scripts. In this study, each task was run 3 blocks and each task
has 6 conditions. In the vector files, I seperated the correct and incorrect
trials. However, one subject has bad performance. She failed all of trials
in one condition in one block. In this case, I dont know how to define the
condition in this block because the correct trial number is 0. If I skip the
condition in that block in the vectors file, SPM2 will pop out a dialog box
and ask me to input the missing defined vector. Is there some way to define
this missing vectors or any other ways to solve this analysis problem? Thank
you very much!
Best wish,
