GelApp 1.0.2

This application provides a sophisticated tool for analyzing gel bands from both agarose and PAGE images, offering automated features that enhance user experience and accuracy. Utilizing an innovative Gabor filter, the app improves band detection, which is particularly beneficial for images of varying quality. Users can easily specify locations of interest by manually drawing boundary boxes or clicking directly on the image, ensuring precision in analysis.

The application supports image uploads from the gallery or Dropbox, adding to its convenience. While scanner-generated images yield optimal results, the app also accommodates photographs taken with mobile devices, provided they are captured from a direct plane relative to the gel.

Key features of the application include:

• Selection between agarose or PAGE gels
• Color identification for marker bands in PAGE gels
• Advanced Gabor imaging filters
• Automated image processing with customizable user input
• Settings and markers can be saved for subsequent use
• User-friendly interface with simple button navigation
• Automated band detection and user-defined boundaries
• Automatic generation of log graphs from markers
• Readings clearly displayed on gel images with highlighted band sizes
• Image cropping before analysis and editing options for unwanted bands
• Differentiated color coding for markers and bands
• Direct access to Dropbox and gallery functionalities
• Compatibility with Sybr Green and EtBr agarose gel analysis

The application offers several advantages for enhancing publication quality:

• Increased accuracy in gel analysis compared to reliance on approximations
• Value-added insights for reports and publications
• An effective teaching resource for science students
• Streamlined analysis that minimizes human error and subjectivity, reinforcing trust in reported values by trainees and inexperienced staff
• On-the-go analysis from smartphones or tablets
• Automated features eliminate the need for graph paper and manual plotting
• No cost associated with app usage
• Operates offline, except when utilizing Dropbox functionality
