结果:主要功能包括:(1)信号处理工具,包括不良通道插值,向下采样,重新引用,过滤,独立成分分析,伪影子空间重建,和功率谱分析,(2)可定制显示多导睡眠图数据和催眠图,(3)事件标记模式包括手动睡眠阶段评分,(4)自动事件检测,包括运动伪影,睡眠纺锤波,慢波和眼球运动,(5)导出主要描述性睡眠结构统计数据,事件统计和可发表的催眠图。
方法:计数绵羊PSG是建立在sleepSMG(https://sleepsmg。sourceforge.net/)。当前软件的范围和功能在EEGLAB集成/兼容性方面取得了重大进展,预处理,伪影校正,事件检测,功能和易用性。相比之下,商业软件可能是昂贵的,并利用专有的数据格式和算法,从而限制了分发和共享数据和分析结果的能力。
结论:睡眠研究领域仍然受到抵制标准化的行业的束缚,防止互操作性,内置计划淘汰,维护专有的黑盒数据格式和分析方法。这对睡眠研究领域提出了重大挑战。免费的需要,可以读取开放格式数据的开源软件对于在该领域取得科学进步至关重要。
BACKGROUND: Progress in advancing sleep research employing polysomnography (PSG) has been negatively impacted by the limited availability of widely available, open-source sleep-specific analysis tools.
METHODS: Here, we introduce Counting Sheep PSG, an EEGLAB-compatible software for signal processing, visualization, event marking and manual sleep stage
scoring of PSG data for MATLAB.
RESULTS: Key features include: (1) signal processing tools including bad channel interpolation, down-sampling, re-referencing, filtering, independent component analysis, artifact subspace reconstruction, and power spectral analysis, (2) customizable display of polysomnographic data and hypnogram, (3) event marking mode including manual sleep stage
scoring, (4) automatic event detections including movement artifact, sleep spindles, slow waves and eye movements, and (5) export of main descriptive sleep architecture statistics, event statistics and publication-ready hypnogram.
METHODS: Counting Sheep PSG was built on the foundation created by sleepSMG (https://sleepsmg.sourceforge.net/). The scope and functionalities of the current software have made significant advancements in terms of EEGLAB integration/compatibility, preprocessing, artifact correction, event detection, functionality and ease of use. By comparison, commercial software can be costly and utilize proprietary data formats and algorithms, thereby restricting the ability to distribute and share data and analysis results.
CONCLUSIONS: The field of sleep research remains shackled by an industry that resists standardization, prevents interoperability, builds-in planned obsolescence, maintains proprietary black-box data formats and analysis approaches. This presents a major challenge for the field of sleep research. The need for free, open-source software that can read open-format data is essential for scientific advancement to be made in the field.
