ROS Bag Filter App

This Python script provides a graphical user interface (GUI) application for filtering ROS bag files using tkinter. It allows users to easily specify input and output bag files, configure time modes, and filter topics based on time intervals. With this tool, working with ROS bag files becomes more intuitive, eliminating the need to use the command line.

Features

• Input and Output Bag File Selection: Easily browse and select your input and output ROS bag files.
• Time Mode Selection: Choose between ROS time and relative time modes for precise filtering.
• Topic Filtering: Filter specific topics from the ROS bag file with ease.
• Time Interval Filtering: Filter messages based on a defined time range.
• User-Friendly GUI: Intuitive interface built with tkinter for a smooth user experience.

Usage
