smoothColumn()¶

smoothColumn(colname, tol=33)¶

Tweaks cell onsets so that there is a maximum of tol milliseconds between each cell. If two cells are less than tol apart, it moves on to the next pair of cells; if there is a larger gap than tol, the second cell’s onset is set to the first cell’s offset.

Parameter	Type	Description
colname	String	Name of the column that you wish to modify.
tol	Integer	The tolerance you are willing to accept between a cell’s offset and the next cell’s onset. By default, this is 33ms.

Returns

Nothing. In addition, smoothColumn() automatically writes its changes back to the spreadsheet, so you do not need to write the changes using setColumn().

Example

The following example checks the “trial” column’s cells to ensure that a maximum of 50ms between a cell’s offset and the subsequent cell’s onset.

require 'Datavyu_API.rb'
begin
   smoothColumn("trial", 50)
end
