Standards and Band Matching
15-11
Display Options
The following options will change how the curve graph is displayed:
Show Standard Points displays the standard data points on the graph. The
standard points in that lane will be marked on the graph as triangles. Note
that known band types will appear marked as standards.
Show Calculated Points displays the calculated points on the graph. The
calculated points in the lane will be marked on the graph as circles.
Perform Log Transform changes the shape of the curve from linear to log.
This will not change the calculated values.
Show Numerical Data of Points displays the value of each band on the graph
next to its corresponding point.
Display Correlation Coefficient displays the correlation coefficient for the
linear, quadratic, and cubic regression models.
Note: The correlation coefficient is a measure of how well the regression model
fits the data. It is the square root of the proportion of total variation that
can be explained by the regression model. A correlation coefficient of
1.000 would indicate 100 percent certainty of fit.
15.1.c Displaying Calculated Values
To view the calculated values of all the bands in your gel image, select Band
Attributes from the Band menu, then select the value to be displayed
(molecular weights, base pairs, etc.).
Values can be displayed and printed in report format using the lane and
match reports (see section 19.2).
15.1.d Saving, Opening, and Deleting Standards
Standards are saved with the image; you can also save copies of them in a
separate archive that is available to all images.
