Model Card for HEST-1k
What is HEST-1k?
- A collection of 1,229 spatial transcriptomic profiles, each linked and aligned to a Whole Slide Image (with pixel size > 1.15 µm/px) and metadata.
- HEST-1k was assembled from 131 public and internal cohorts encompassing:
- 26 organs
- 2 species (Homo Sapiens and Mus Musculus)
- 367 cancer samples from 25 cancer types.
HEST-1k processing enabled the identification of 1.5 million expression/morphology pairs and 76 million nuclei
Updates
21.10.24: HEST has been accepted to NeurIPS 2024 as a Spotlight! We will be in Vancouver from Dec 10th to 15th. Send us a message if you wanna learn more about HEST ([email protected]).
23.09.24: 121 new samples released, including 27 Xenium and 7 Visium HD! We also make the aligned Xenium transcripts + the aligned DAPI segmented cells/nuclei public.
30.08.24: HEST-Benchmark results updated. Includes H-Optimus-0, Virchow 2, Virchow, and GigaPath. New COAD task based on 4 Xenium samples. HuggingFace bench data have been updated.
28.08.24: New set of helpers for batch effect visualization and correction. Tutorial here.
Instructions for Setting Up HuggingFace Account and Token
1. Create an Account on HuggingFace
Follow the instructions provided on the HuggingFace sign-up page.
2. Accept terms of use of HEST
- On this page click request access (access will be automatically granted)
- At this stage, you can already manually inspect the data by navigating in the
Files and version
3. Create a Hugging Face Token
Go to Settings: Navigate to your profile settings by clicking on your profile picture in the top right corner and selecting
Settings
from the dropdown menu.Access Tokens: In the settings menu, find and click on
Access tokens
.Create New Token:
- Click on
New token
. - Set the token name (e.g.,
hest
). - Set the access level to
Write
. - Click on
Create
.
- Click on
Copy Token: After the token is created, copy it to your clipboard. You will need this token for authentication.
4. Logging
Run the following
pip install datasets
from huggingface_hub import login
login(token="YOUR HUGGINGFACE TOKEN")
Download the entire HEST-1k dataset:
import datasets
local_dir='hest_data' # hest will be dowloaded to this folder
# Note that the full dataset is around 1TB of data
dataset = datasets.load_dataset(
'MahmoodLab/hest',
cache_dir=local_dir,
patterns='*'
)
Download a subset of HEST-1k:
import datasets
local_dir='hest_data' # hest will be dowloaded to this folder
ids_to_query = ['TENX96', 'TENX99'] # list of ids to query
list_patterns = [f"*{id}[_.]**" for id in ids_to_query]
dataset = datasets.load_dataset(
'MahmoodLab/hest',
cache_dir=local_dir,
patterns=list_patterns
)
Query HEST by organ, techonology, oncotree code...
import datasets
import pandas as pd
local_dir='hest_data' # hest will be dowloaded to this folder
meta_df = pd.read_csv("hf://datasets/MahmoodLab/hest/HEST_v1_1_0.csv")
# Filter the dataframe by organ, oncotree code...
meta_df = meta_df[meta_df['oncotree_code'] == 'IDC']
meta_df = meta_df[meta_df['organ'] == 'Breast']
ids_to_query = meta_df['id'].values
list_patterns = [f"*{id}[_.]**" for id in ids_to_query]
dataset = datasets.load_dataset(
'MahmoodLab/hest',
cache_dir=local_dir,
patterns=list_patterns
)
Loading the data with the python library hest
Once downloaded, you can then easily iterate through the dataset:
from hest import iter_hest
for st in iter_hest('../hest_data', id_list=['TENX95']):
print(st)
Please visit the github repo and the documentation for more information about the hest
library API.
