Hi Freesurfers,

When conducting ROI analyses in Stable 5, is there a way to generate a mean functional baseline offset value within the ROI which can be used to help calculate percent signal change? This would correspond to the value from row 4 in the output file generated by roisummary-sess in Stable 4.

Thanks,

Adam

PS: Here are examples of the commands I've used in Stable 5 to generate ROI Data:

funcroi-config -analysis SIRP_Stable5 -label LH_16MTH_7v1_DLPFC -roi MTH_7vFix_DLPFC.roicfg -contrast Cond7vFix -sign abs -thresh 1.3

funcroi-sess -roi MTH_7vFix_DLPFC.roicfg -sf /cluster/roffman/users/Stable5_PerRun/Subject_Files/16_PreScan_Genotyped_MTH

funcroi-table-sess -roi MTH_7vFix_DLPFC.roicfg -sf /cluster/roffman/users/Stable5_PerRun/Subject_Files/16_PreScan_Genotyped_MTH -c Cond7vFix -o /cluster/roffman/users/Stable5_PerRun/DLPFC_ROI_7vFix_MTH
