Miss_Teng is an artificially constructed MSI-like dataset created for engineering-level testing and workflow demonstration of the R package ARBO.
This repository provides a large MSI-like example dataset in imzML format for evaluating the computational handling of large inputs in ARBO.
The dataset has the following characteristics:
- 1,000 features
- 1,572,864 spectra / pixels
- Spatial dimensions: 1024 × 1536
- Mass range: 50–1500
- Centroided: FALSE
Miss_Teng was not generated from a real mass spectrometry imaging experiment.
Instead, it was artificially constructed using a portrait-style image as a visual template. The image was derived from the author's own portrait and further transformed using AI-assisted image generation/stylization. The final image is a stylized animated portrait resembling a young woman, but it does not depict a real female participant.
The image was used only as the visual basis for constructing this MSI-like dataset.
Miss_Teng was created primarily to test the processing capability of ARBO on large MSI-like data. It can be used for software-level and workflow-level testing, including:
- imzML data handling
- spectra matrix extraction
- preprocessing
- dimensionality reduction
- clustering
- spatial visualization
- workflow demonstration
- scalability-oriented testing
This dataset should therefore be understood as an engineering test case or scalability-oriented example, rather than a biological or analytical benchmark dataset.
The m/z values, spectral patterns, and spatial signal structures in this dataset do not carry real biochemical, pathological, or experimental meaning.
Accordingly, this dataset is not suitable for:
- biological interpretation
- metabolite annotation
- scientific inference
- serious analytical validation
- formal benchmark comparisons between MSI methods
Please do not use this dataset as a formal benchmark dataset for methodological comparison in scientific publications.
This repository may include:
- the Miss_Teng imzML-based dataset
- the portrait-style source image used as a construction template
- HTML files showing ARBO-based processing workflows and analysis results
The HTML files document example analyses of this dataset using ARBO, including processing steps and visualization results.
The portrait-style image included in this repository is provided only to help document and understand the origin of the synthetic dataset construction.
The image is a synthetic, AI-transformed derivative of the author's own portrait. It is not a real MSI sample image, not a biological reference image, and not a ground-truth annotation.
The image is included for documentation purposes only. Reuse, redistribution, or use of the image outside the context of this repository is not recommended without permission from the author.
Miss_Teng is a synthetic MSI-like dataset constructed solely for software testing, workflow demonstration, and scalability evaluation. It is not a real experimental MSI dataset and should not be used for biological interpretation or formal scientific benchmarking.
