What it is
Single-cell RNA-seqGene activity measured in thousands of individual cells, so cell types can be told apart. Read from the summary: GEO's own type field only says 'expression profiling by sequencing', so confirm it in the paper.

Data you can get
A processed table (series matrix) and supplementary files from NCBI; the raw sequencing reads from ENA. Which of these hold counts depends on the study, so check the file list.
Paper
Microglia and monocyte-derived macrophages drive progression of pediatric high-grade gliomas and are transcriptionally shaped by histone mutationsImmunity · 2024
Summary (written by the submitters)
Pediatric high-grade gliomas, including diffuse midline gliomas (DMG), harbor mutually exclusive tumor location specific histone mutations. Using immunocompetent genetically engineered mouse models, we demonstrate the predominant non-neoplastic cell population are infiltrating myeloid cells, including peripheral monocytes and brain resident microglia.
Read the full summary ↓
Single cell RNA sequencing, flow cytometry, and immunohistochemistry demonstrate the presence of unique myeloid cell populations distinctly shaped by the specific histone mutation. Disease associated myeloid cell phenotypes are identified, resembling those found in other neurodegenerative diseases, and demonstrate immune permissive characteristics. H3.3K27M DMGs, the most aggressive DMG subtype, demonstrate enrichment of disease associated myeloid cells as well as proliferating myeloid and tumor cells.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE245716_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: Single-cell studies usually ship their counts as 10x files (matrix.mtx, barcodes.tsv, features.tsv), an .h5 file, or an .rds / .h5ad object that Seurat or Scanpy can open. Look for those among the supplementary files.

Also filed as BioProject PRJNA1029612 and SRA study SRP467181. Searching any of these in the dataset finder brings you back here.
