Declan Getting Started

Initial install

1. grab the kymflow.app.zip off box
2. grab the declan-stall-v1.zip off box
3. uncompress both files

Always work locally, DO NOT work on files that are on box.

We will be working in the raw data folder you just unzipped, declan-stall-v1/.

All your work will be saved into declan-stall-v1/. You can then zip the entire folder and put it back on box for me to analyze the results. Important when putting the new declan-stall-v1.zip on box, be sure to put it into a new folder, do not replace the original declan-stall-v1.zip on box.

Now that you have a local copy of declan-stall-v1/. Run the KymFlow app ...

Once the KymFlow app is running ...

Click 'open csv', find you local declan-stall-v1/ folder and open the provided declan-random-v1.csv

This will populate KymFlow with 50 files for scoring.

We are loading and analyzing a random subset of tif files specified in declan-random-v1.csv

You need to use 'Open CSV' and then insure you are looking at a list of 50 tif files.

The main window will look like this:

On top is a table/list of all tif files.

Single click a file will:

• Display the kym image (gray)
• Display its radon velocity analysis (red)
• Populate the 'kym events'. In this example there are two 'kym events' shown in the lower table

To add your own User Added events that will represent a stall:

• Zoom in on the kymograph/velocity plot (mouse click + drag)
• Click 'Add Event' -> select the start/stop time of the event visually (again with a click+drag in the kymograph/velocity plot)
• You will then see your new 'User Event' in the event list. User events are displayed in the velocity plot as yellow rectangles.
• The evnts you add will have Type 'User Added'
• You can further classify your 'User Added' events by a double-click on 'User Type' and select from: unreviewed, true_stall, reversal, other.

Some GUI niceties

• Keyboard enter will always set the view to full scale. You can also double-click on the plot to set full scale.
• When you are zoomed in, use the '<' and '>' buttons or keyboard left-arrow and right-arrow to scroll throught the kymograph.
• You can always go to the previous and next file in the list with keyboard shift + up-arrow and down-arrow.

Blind analysis

To turn on blind analysis. Go to the options toolbar and click on the 'Blinded Analysis' checkbox.

Important. Blinded analysis is a honesty contract. The gui will in general blind your analysis by not showing filenames, dates, treatments, conditions, etc. There are plenty of ways around it. Be honest!!!

Always save your work

As you add user events, the top table of files will show which have been edited with a red X.

Save all your work with 'Save All' button.

When you quit KymFlow, you will see a warning "Do you really want to quit?".

If you still need to save, click Cancel, save your work, and then quit again.

What is next

This is just the first step.

Score all 50 files in declan-stall-v1/ declan-random-v1.csv. Zip the declan-stall-v1/ and put the zip into a new folder on box.

This little tutorial is really the beginning of a lot of fun with GUIs. There is a ton more but I will leave it at that for now.
