* Open and run `annotation_example.m`. This will start the GUI on 5 images provided in `foci-annotator/data_folder`.
To annotate images:
* Left-right arrows are used to change images.
* Up-down arrows are used to change radius.
* Clicking adds annotations.
*Shift-d allows deleting one annotation by clicking close to it.
* Zooming and panning works as normal in matlab, but must be exited to continue adding annotations.
* S saves annotations as a `.mat` file and a `.txt` file. NOTE: previously saved files will be overwritten.
* Left-right arrows are used to change between images.
* Up-down arrows are used to increase or decrease radius by one (starts with five).
* Clicking adds annotations (if in view limits and outside a previously added annotation).
*D (shift-d) allows deleting one annotation by clicking close (less than five times radius) to it.
* Zooming and panning works as normal in Matlab, but must be exited to continue adding annotations.
* S saves annotations as a `.mat` file and a `.txt` file with csv formatted text. Columns are: image number, transverse (x)coordinate, axial (z) coordinate, radius (in pixels). NOTE: previously saved files will be overwritten.
