Patchseq Data of T1D Donor Islets vs ND Matched Controls

GSE270484 Homo sapiens (human) Single-cell RNA-seq 958 samples Submitted 2024/06/25 Platform GPL24676
At a glance

Single-cell RNA-seq · human · 958 samples

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.
Organism
Homo sapiens (human)
Samples
958 samples: 34 conditions, mostly with about 12 replicates eachGroups are read from the sample names, not from the paper. Check the list below.
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.

Summary (written by the submitters)
Will be updated closer to manuscript finalization. Patchseq allows for combined electrical and transcriptomic data to be obtained at single cell resolution. Here we performed patchseq on islet cells from human donors

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 GSE270484_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 PRJNA1126733 and SRA study SRP515359. Searching any of these in the dataset finder brings you back here.

Study design
34 conditions, mostly with about 12 replicates each
A3B ×12 A3C ×12 A3D ×12 A3E ×12 A3F ×12 A3G ×12 A3H ×12 B3A ×12 +26 more

Supports a between-group comparison across 400 samples.

How we read this: 34 replicated groups read from the first 400 of 958 sample titles; they account for 400 of them. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
