三、UniExplorer软件官方说明书核心规则(Software User Guide)
1. 语言设置官方标准步骤(原文操作路径)
1. Top menu bar:Tools → Options → Advanced tab;
2. Language dropdown select:Chinese (Simplified);
3. Save setting, exit software via File→Exit(not close window directly);
4. Restart program to activate Chinese interface;
5. Garbled text fix:modify Windows system non-Unicode locale to Chinese (Simplified, China)。
2. 三大底层授权算法(手册明确版权算法)
1. SESA algorithm (Segmentation and Extraction of Surface Area):static impurity filtering,automatically eliminate medium crystal, drug precipitate, bubble, only retain microbial valid pixels(静态杂质过滤,长周期监测抗干扰核心);
2. BCA algorithm (Background Corrected Absorption):biomass area quantification,sensitivity 250× higher than standard OD microplate reader(生物量面积定量,灵敏度为传统OD法250倍);
3. TA algorithm (Total Absorption):equivalent OD value,for parallel comparison with turbidity method;
4. Supplementary morphological segmentation algorithm:20+ morphological parameters for bacteria, yeast and filamentous fungi(20余项形态学量化指标)。
3. 内置动力学拟合数学模型完整列表(Official Built-in Models)
1. Modified Gompertz Model(default recommended for fungi spore germination);
2. Baranyi-Roberts Model(predictive microbiology gold standard for lag phase calculation);
3. Logistic Model;
4. Richards Generalized Growth Model;
5. Exponential Growth Model;
6. Monod Substrate Limitation Model;
7. Linear Regression Model;
All models automatically calculate λ lag phase, μmax maximum growth rate, Xmax maximum biomass, R² goodness of fit。
4. 图像导出与数据导出官方权限说明
1. Raw image export permission (full licensed version only):
- Single well single time-point best-focus original TIFF/JPG lossless pictures;
- Full Z-stack layered stack images per well;
- SESA binary segmentation annotated comparison images;
- Time-lapse MP4 video batch export;
File naming automatically contains experiment ID, well position, time point, stack layer for traceability;
2. Morphological parameter export:fully customizable checkbox selection,support two export dimensions:① single individual cell/hypha detailed data;② per-well average aggregated data,output format Excel/CSV;
3. Trial version limitation:only basic BCA biomass data available, no morphological parameter export and limited image export quantity。
5. 数据溯源与审计规范(英文手册合规条款)
All exported images, kinetic curves, parameter tables are one-to-one corresponding;complete experiment package can be packaged and migrated to another computer for re-analysis, meeting laboratory data retention and method validation requirements.
四、官方标注应用场景与性能优势(Application Note Key Points)
1. Antimicrobial susceptibility test (AST/MIC):results available within 4 hours, 4 times faster than CLSI standard broth microdilution method (16–20h), adopted by US CDC for resistant bacteria detection;
2. Fungal spore germination, preservative inhibition efficacy, long-term dormancy spore resuscitation monitoring (up to 10+ days continuous run);
3. Morphological phenotypic analysis:β-lactam induced bacterial filamentation, abnormal hyphae, spore swelling quantification;
4. Methodological verification:correlation validation between imaging area and CFU plate counting, establish alternative quantitative method;
5. Core advantage over OD reader:OD cannot distinguish biomass increase and morphological abnormality, this system realizes quantity quantification + visual phenotype double verification。
五、说明书明确风险警示与禁忌条款(Safety & Warning)
1. Do not frequently move the instrument after installation, vibration will cause optical axis offset and positioning deviation;
2. Long-period incubator internal operation: avoid condensate dripping on the top optical window;
3. Do not set ultra-high frequency continuous scanning, cumulative weak light will theoretically cause negligible slight stress to sensitive spores;standard 30min–4h interval scanning is completely safe;
4. The instrument cannot modify built-in algorithm formulas and add custom mathematical models, only select existing parameters for export.
