title: Hematopathologist-annotated mass cytometry dataset of acute myeloid leukemia diagnostic specimens

description: This dataset comprises hematopathologist-annotated single-cell data from
 patients with Acute Myeloid Leukemia (AML), sourced from FlowRepository
 (ID: FR-FCMZ2E7). The dataset includes normalized, singlet-gated events
 with annotations provided by the authorship team of Tsai et al., excluding
 one patient diagnosed with Myelodysplastic Syndrome (MDS) due to
 diagnostic ambiguity. To align with blast enumeration standards and
 pathology laboratory procedures, only CD45+ hematopoietic lineage cells
 were included in the analysis. Data preprocessing followed standard mass
 cytometry protocols, including hyperbolic arcsine transformation with a
 cofactor of 5, scaling markers to their 99.9th percentile, and exclusion
 of cells with marker values exceeding this threshold to remove artifacts
 and outliers. This dataset, processed using the R package tidytof, offers
 a high-quality resource for researchers investigating AML through
 single-cell analysis.

 leukemia diagnostic specimens
 [https://doi.org/10.5061/dryad.jq2bvq8kj](https://doi.org/10.5061/dryad.jq2bvq8kj) ## Description of the data and file structure This dataset, originally collected to study single-cell morphometric profiling in AML, has now been annotated by a hematopathologist to provide single-cell labels distinguishing cancerous blasts from healthy bone marrow cells. These expert annotations, combined with the high-dimensional molecular and morphological data, make the dataset uniquely suited for developing and validating machine learning methods for disease-associated cell identification. The addition of cell-level annotations enables applications such as training classifiers to identify leukemia cells and selecting biologically meaningful features. This resource supports advances in single-cell data analysis and provides a valuable benchmark for studying acute myeloid leukemia and related conditions. ### Files and variables #### File: aml_dataset_for_dryad.csv **Description:** This dataset consists of single-cell measurements from Acute Myeloid Leukemia (AML) samples collected via mass cytometry. Each row represents a single cell, and each column contains either a sample-level label, a cell-level label, or marker intensity measurements. The dataset has been annotated by a hematopathologist, distinguishing cancerous blasts from healthy bone marrow cells. There are 13 AML patients and 3 non-AML patients.  ##### Variables * patient: Unique identifier for each patient in the dataset, taken from the original paper. `patient` IDs that begin with the string "AML" are AML patients; the remaining patients are non-AML patients.  * patient_label: Clinical label of the patient sample. Possible values: * `aml`: Indicates the sample originates from a patient diagnosed with Acute Myeloid Leukemia. * `healthy`: Indicates the sample originates from a patients not diagnosed with Acute Myeloid Leukemia. * cell_label: Hematopathologist-provided label for each cell.

Written informed consent was obtained from all participants, including consent for future research use and public data sharing of de-identified samples. The data submitted to Dryad have been fully de-identified in accordance with HIPAA and international data protection guidelines. Specifically, all direct personal identifiers (e.g., names, dates of birth, medical record numbers) were removed prior to analysis. Clinical metadata were limited to non-identifiable variables. As such, the dataset is compliant with applicable regulations governing the sharing of human subjects data and is suitable for public domain distribution via Dryad.
