Create an example page

First, determine a page name for your example, such as "Instructions for Adding Your Own Example". The complete page name would be "Support:Documents:Examples:Instructions for Adding Your Own Example" in this case. Copy and paste the complete page name into the search box next to the "Go to" button. Click "Go to". You will be guided to a new page with no content in it. In the editing box of this page, write your example.

Estimating Input Function Parameters Simultaneously with Flow

This example demonstrates an approach to simultaneously estimating input functions parameters along with blood flow in the context of the PET blood flow model. The flow model has one tissue compartment and (radioactive) water in the blood is assumed to rapidly exchange with the water in the tissue. The tissue model has two rate constants: K1 and k2.

Instead of estimating K1 and k2, it sometimes is advantageous estimate a different set of parameters defined as

lambda = K1/k2 and F = K1.

The interpretation is that F is blood flow (perfusion) per unit volume of tissue and lambda is the ratio of tissue to blood concentration at equilibrium.

To use this parameterizatio in COMKAT, one needs to express the rate constants in terms of lambda and F:

K1 = F k2 = K1/lambda



There are

Text

Write some introduction to your example.

Code

You can put code in a different format using <pre> tags like:

For text that you want to appear as part of a MATLAB function or program, encase it inside a "pre" block.
Line 2 of pre block
    Line 3 (indented) of pre block.

Edit the current page to see how this is done.

Figures

Remember to include figures and plots in your example to make it look pretty and convey information. To insert a figure, create a figure file in png (preferred) or other graphic format.

figure
plot(1:10)
title('Example Figure')
ylabel('y-axis label')
xlabel('x-axis label')
set(1,'PaperPosition',[0.25 2.5 3 2])
print -dpng ExampleFigure.png


Next, upload the image file ("upload file" at the bottom of any wiki page) giving it a unique name.


Use double-square brackets to insert the figure into the page

Edit the example index page to include your example in the list

Add your new example to the list of examples on the example index page by adding a line like this to the index page:

[http://comkat.case.edu/comkat/comkat_wiki/index.php?title=Support:Documents:Examples:Instructions_for_Adding_Your_Own_Example The title of you example]

Within the brackets, the first part is the URL address to your example page. Then you type your example title following that address. On the index page it will look like:

The title of you example


That is it. It is so simple that even a caveman (or professor) can do it.
