[Freesurfer] Is the slice delay of each slice needed for slice time correction with preprocess-sess?

External Email - Use Caution

Dear all,

Have I understood correctly that the slice delay of each slice is not needed when performing slice time correction with preprocess-sess?

I am processing an open OASIS fMRI dataset. The dataset has fMRI data in nifti format and JSON files that contain information about the data. In the instructions they say: "Slice timing is included in the JSON when available. Some original DICOM files did not have slice timing info. When slice timing information is unavailable use the ratio TR/#slices."

The data is collected with a Siemens scanner. If the slice timing is available it seems to be interleaved:

"SliceTiming": [ 1.1025, 0, 1.165, 0.059999999999999998, 1.2250000000000001, 0.1225, 1.2875000000000001, 0.1825, 1.3474999999999999, 0.245, 1.4099999999999999, 0.30499999999999999, 1.47, 0.36749999999999999, 1.5325, 0.42749999999999999, 1.595, 0.48999999999999999, 1.655, 0.55000000000000004, 1.7175,

Could I just run slice time correction with the siemens option?

Best regards, Maria
