Hi, Experts.
I'm trying task fMRI analysis using SPM.
There are two runs for each subject, and each run has been preprocessed to 4D NIFTI data.
1) Go noGo task: response on high tones (a 4D Nifti data with 200 volumes)
2) Go noGo task: response on low tones (a 4D Nifti data with 200 volumes)
I want to test following contrast.
(noGo_lowtone + noGo_hightone) - (noGo_lowtone + noGo_hightone).
how can I deal with 2 NIFTI data for 1st level analysis?
Thanks,
YM Huh
