黑沙们展示is an interactive and user-friendly image analysis software tool to investigate the cell biology of common used bacterial species (e.g. Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, etc.) and stalk-forming bacteria (e.g. Caulobacter crescentus, Hyphomonas neptunium, Brevundimonas aveniformis, etc.). BacStalk uses phase contrast, brightfield, and/or fluorescence images to segment bacteria and generate demographs, kymographs, histograms, scatterplots. For stalked bacteria, BacStalk can also identify hardly-visible bacterial stalks to observe stalk formation dynamics and bud cell growth. Fluorescence images can be used to measure protein expression patterns along cells and stalks.

Bacstalk使用非常直观和现代的图形用户界面，并提供文件处理，元数据提取，单元/杆/芽分割，单元跟踪，数据分析和可视化所需的所有工具。Bacstalk生成出版级数字，只需点击几下即可。虽然Bacstalk基于MATLAB软件，但它不需要使用任何编程知识。
