CellRank a toolkit to uncover cellular dynamics based on Markov state modeling of single-cell data. Detailed information about CellRank can be found here: https://cellrank.readthedocs.io/en/stable/.


  • 1.5.1


  • python

  • python3


You can load the modules by:

module load biocontainers
module load cellrank/1.5.1


The CellRank container also contained scVelo and scanpy. When you want to use CellRank, do not load scVelo or scanpy.

Interactive job

To run CellRank interactively on our clusters:

salloc: Granted job allocation 12345869
salloc: Waiting for resource configuration
salloc: Nodes bell-a008 are ready for job

Batch job


Using #!/bin/sh -l as shebang in the slurm job script will cause the failure of some biocontainer modules. Please use #!/bin/bash instead.

To submit a sbatch job on our clusters:

#SBATCH -A myallocation     # Allocation name
#SBATCH -t 10:00:00
#SBATCH -n 24
#SBATCH --job-name=cellrank
#SBATCH --error=%x-%J-%u.err
#SBATCH --output=%x-%J-%u.out
