5-38 Image Optimization
Delete ROI
Press <Clear> to clear out the last ROI; click [Delete All] on the soft menu to clear out
all ROIs.
The corresponding traces for the deleted ROIs are erased from the plot.
Deleting an ROI causes the ROIs to be deleted from all frames in the analysis loop.
Tips:
The saved ROIs can be a mixture of elliptical and freehand ROIs.
Elliptical ROIs can be positioned in any manner that keeps their center within the
image boundaries. In the case that part of the ROI is outside the image boundary,
only data from within the image boundary is used for calculating the mean
intensity value.
When the user repositions an ROI, the old trace data is erased from the plot and
the trace data for the new position re-plotted.
Hide/Show
Click [Hide] or [Show] on the soft menu to hide or display the analysis curve area.

All displayed ROI traces are saved in the exported file.
The parameters are included in the trace file if the user has fixed a ROI.
After the exporting is succeeded, a .BMP format image is displayed in the
thumbnail area at the lower part of the screen.
Only data from the user selected image range is included in the exported trace
file.
