What it is
RNA-seq (gene expression)Gene activity measured by sequencing. The summary does not mention single-cell work, so this is most likely bulk: one average per sample, the usual starting point for comparing groups.
Organism
Mus musculus (mouse)
Samples
138 samples: 138 samples, each with a distinct title — no replicated groupsGroups 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)
Striatum and cortex were isolated from 12-month-old Msh2 flox/flox or Msh2 +/flox mice crossed with the Rgs9Cre+/- and Q140 knock-in (KI) HD mice and their respective controls. Transcriptomic analysis (RNASeq) was performed on 9 genotypes: Msh2fl/fl, Het (Q140) KI X Msh2fl/fl, Rgs9Cre+/-, Het (Q140) KI X Rgs9Cre+/-, Het (Q140) KI X Rgs9Cre+/- X Msh2+/fl, Rgs9Cre+/- X Msh2fl/fl, Het (Q140) KI X Rgs9Cre+/- X Msh2fl/fl, Het (Q140) KI, and WT; 6-8 replicates per genotype.

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 GSE229815_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.

Raw reads on ENA ↗

What the files usually look like: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA956257 and SRA study SRP432856. Searching any of these in the dataset finder brings you back here.

Study design
138 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 138 sample titles: 138 distinct titles with little repetition. 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.
