AFNI 3D Temporal Concatenate (3dTcat)¶
Library: AFNI | Docker Image: brainlife/afni
Function¶
Concatenates datasets along the time dimension or selects specific sub-bricks from 4D data.
Modality: 3D or 4D NIfTI/AFNI volumes.
Typical Use: Combining runs, removing initial steady-state volumes.
Key Parameters¶
-prefix (output),
Key Points¶
Sub-brick selectors allow flexible volume selection: [0..5] for first 6, [0..$-3] to skip last 3.
