This process pads the top and/or bottom of traces in a TWT volume with zeros, simple extrapolation or mirrored samples. If ramping is selected, a linear ramp is applied across the padded values.
- In the Process tab, click the Add icon and select New Process.
- Select Trace Padding and type a name for the process.
In the Details Panel, select the Volume to pad.
- Pad at the start/end of the trace (ms) — Positive values will add additional samples; negative values will trim samples. Pad times will be rounded to the nearest sample.
- Value of padded samples — Zeroes, mirrored, mirrored then ramped, or Pad start with first sample value and pad end with last sample value.
