Keep or delete specified template points. Points will be renumbered and line definitions will be updated. If all points in a line are deleted, the line will be removed. POint indexing is 0-based, so the first two points (usually the pupils) are 0 and 1.
Arguments
- stimuli
list of stimuli
- ...
vectors of points to keep or delete
- keep
logical; whether to keep or delete the points
