5.3.7.4 Shift Marker Occurrences
This item opens the Shift Marker Occurrences dialog box. An illustration of the
dialog box follows:
Use this dialog box to add a constant offset, which can be negative, to all
timestamps of a marker. It is useful for aligning neural data with the video data.
• Marker - Select a marker to shift from the drop-down list.
• First Occurrence Time - This is the time that the first occurrence of the
marker appears.
• Last Occurrence Time - This is the time that the last occurrence of the
marker appears.
• Range - This is the time span between the first and last occurrences.
• Shift by _ secs - This selection shifts the occurrences by a constant amount.
Enter the amount of shift directly in the edit box.
• Shift so that first Occurrence is at time _ secs - This selection calculates
the shift amount by determining how much the first occurrence of the
selected marker must be shifted to make it equal to the specified time. Cine-
Plex then applies this shift amount to all occurrences.
• Shift so that the first Occurrence is at time of Marker - This selection
shifts the time to that of another marker occurrence. Select the shift-determining
marker from the drop list.
• Occurrence - Enter which occurrence of the shift-determining marker to
use by typing its 1-based index into the edit box.
