Choose any combination of VOI and fMRI

For each fMRI and VOI:

• Go to 1st level SPM

  • E.g.: …\fMRIpreprocess\…\SPMboxcar_s6wcrLinear\

• Create a VOI subfolder

  • E.g.: …\fMRIpreprocess\…\SPMboxcar_s6wcrLinear\VOI\Hipp L\

• Get F-contrast for All Effects (calculate if necessary)

• Run Results with no threshold (P = 1 => F = 0) and VOI as mask

  • batch file: job_1stlevelVOIresults4ppi

• Extract Eigenvariate using VOI as mask, no adjustment

  • Saves in VOI_…mat

  • Move to VOI folder

• Create PPI variable (SPM PPI)

  • Saved in PPI_…mat in VOI folder

• Create new SPM model with PPI variables as regressors

  • Saved in VOI folder

  • batch file: job_design_ppi

• Estiamte model

• Create T contrast of 1st variable (interaction)

  • con_0001.nii

• Copy file to group folder for 2nd level analysis (prepend filename with study name)

CSPM will create a new fMRI measure than can be analysed with the SPM. (Need to re-load).
