Overview

ui2.py is a powerful GUI-based browser written in Python. ui2.py allows you to rapidly scroll through large movies and overlay the results from whisker tracking. ui2.py can also be used to manually correct the results from automated whisker tracking.

If no dataprefix is given, a default set will be created. The prefix will be used to load/save the appropriate files. Ordering of the filenames isn't important. Filetype is detected according to the file extension.

Keyboard Controls

key

Mouse Controls

Action

function

Right click

Mark seed for whisker tracking. Attempt backbone tracing. Draw traced whisker backbone. Advance 1 frame.

Left click

Add nearest segment within cursor to current whisker. If no segment found in cursor, clear any segments in that frame assigned to the whisker. Advance 1 frame.

Mouse wheel up

Advance 1 frame

Mouse wheel down

Rewind 1 frame

Notes

If filenames are not completely specified, default names will be guessed.

If an existing data file is found, the whisker data will be loaded.

Normally the left and right arrow keys advance or rewind by one frame. Holding down shift, ctrl, and/or alt keys will increase the step size by 10x each. Hence, holding shift and ctrl (or ctrl and alt, etc...) results in a 100 frame step. Holding shift ctrl and alt and pressing left or right, jumps 1000 frames.

The face hint is used when saving to a .measurements file. The .measurements file contains measures of follicle features and the identity of segments. Some of these measurements require approximate knowledge of the center of the whisker pad, which is indicated by the face hint. Currently, the hint only takes values of left,right,top or bottom that indicate the side of the movie the face is on. These options work for a specific class of data where the image is cropped so the mouse's face is on one side.
