The complete FlowSOM package known from R, now available in Python!
Please refer to the documentation. In particular, the following resources are available:
You need to have Python 3.9 or newer installed on your system. If you don't have Python installed, we recommend installing Mambaforge.
There are several alternative options to install FlowSOM:
- Install the latest development version:
pip install git+https://github.com/saeyslab/FlowSOM_PythonStarting from an FCS file that is properly transformed, compensated and checked for quality, the following code can be used to run the FlowSOM algorithm:
# Import the FlowSOM package
import flowsom as fs
# Load the FCS file
ff = fs.io.read_FCS("./tests/data/ff.fcs")
# Run the FlowSOM algorithm
fsom = fs.FlowSOM(
ff, cols_to_use=[8, 11, 13, 14, 15, 16, 17], xdim=10, ydim=10, n_clusters=10, seed=42
)
# Plot the FlowSOM results
p = fs.pl.plot_stars(fsom, background_values=fsom.get_cluster_data().obs.metaclustering)
p.show()See the changelog.
