Cluster dynamics in macroscopic photoactive particles

This repository contains the clusters detected in the experiments reported in "Cluster dynamics in macroscopic photoactive particles" (authors: Sára Lévay, Axel Katona, Hartmut Löwen, Raúl Cruz Hidalgo, and Iker Zuriguel). Experiments are done for five different total populations (N_T=40, 60, 80, 100, 120), and seven different homogeneous activity levels (P=23, 33, 43, 52, 60, 67, 72 mW), each repeated 5 times. Clusters were detected in all experiments, and their time evolution is published in this dataset. For the homogeneous illumination: Each experiment has an ID, which can be found in metadata.csv, along with N_T and P. cumulative_clusters.csv contains the time evolution for all the clusters detected in these experiments.The columns: 1: cluster ID, 2: frame number, 3: size of the cluster, 4: experiment ID.The time is measured in frames, and the videos were recorded with 30 fps. For inhomogeneous illumination: We have also conducted experiments to detect the cluster formation and dissolution.To induce cluster growth, we applied low illumination to one half of the arena, and once a large cluster was formed, we switched to a high, homogeneous illumination to induce cluster dissolution. The time evolution of cluster growth and dissolution is available in crdata_reduced.csv and dsdata_reduced.csv, respectively. A pseudo-code is provided in prepare_hist.md to process the cluster dissolution statistics and obtain the disassociation probabilities presented in Fig.5(e) of the manuscript. Additional code is available on GitHub.本仓库收录了论文《宏观光活性粒子的团簇动力学》（Cluster dynamics in macroscopic photoactive particles，作者：Sára Lévay、Axel Katona、Hartmut Löwen、Raúl Cruz Hidalgo 及 Iker Zuriguel）中报道的实验所检测到的团簇（cluster）数据。 本研究共设置5组不同的总粒子数（N_T=40、60、80、100、120）与7组不同的均匀光照活性水平（P=23、33、43、52、60、67、72 mW），每组实验均重复5次。所有实验均成功检测到团簇，其时间演化数据已收录至本数据集。 ### 均匀光照场景 每个实验均配有唯一标识符（ID），可在metadata.csv文件中查询，该文件同时记录了对应实验的总粒子数N_T与活性水平P。 cumulative_clusters.csv 文件收录了所有实验中检测到的团簇的时间演化数据，各列依次为：1. 团簇ID；2. 帧编号；3. 团簇尺寸；4. 实验ID。时间以帧为单位计量，实验视频的采集帧率为30 fps。 ### 非均匀光照场景 我们还开展了针对团簇形成与解离过程的实验：为诱导团簇生长，我们将实验腔室的一半区域设置为低光照环境；待大型团簇形成后，切换至均匀高光照环境以诱导团簇解离。 团簇生长与解离的时间演化数据分别收录于 crdata_reduced.csv 与 dsdata_reduced.csv 文件中。 prepare_hist.md 文件中提供了一段伪代码，用于处理团簇解离统计数据，以复现论文中图5(e)所示的解离概率结果。 额外的代码已上传至GitHub平台。
