Offset Tab

Use the Offset tab to access specialized offset channel operators used in mathematical expressions.

Each tab item includes a tooltip that shows the required arguments and a brief description of the function.

Button	Syntax	Definition
	.at(fid)	Returns the value of a channel at a specific fiducial within the current line
	.first	Returns the first value of a channel in the current line.
	.last	Returns the last value of a channel in the current line.
	.offset(fid)	Returns the channel value offset by the specified units of fiducials. The value in brackets represents n units of fiducials, not an index.If fiducials increment in values smaller than 1 (e.g., 0.1), ensure the offset value aligns with the fiducial increment.

Temporary variables (preceded by the @ operator) are not supported in the new Offset dot (.) functions.

Array elements (e.g., C1[1]) are currently unsupported by the Offset dot functions.
