Compass¶
Compass is an algorithm to characterise the metabolic state of cells based on single-cell RNA-Seq and flux balance analysis (FBA).
Compass is available as a module which wraps an Apptainer container on Apocrita.
Usage¶
To run the default installed version of Compass, simply load the
compass module:
$ module load compass
$ compass -help

Example job¶
Serial job¶
Here is an example job running on 1 core and 1GB of memory using the
homo_sapiens species:
#!/bin/bash
#$ -cwd
#$ -j y
#$ -pe smp 1
#$ -l h_vmem=1G
#$ -l h_rt=1:0:0
module load compass
compass --data expression.tsv \
--num-processes "${NSLOTS}" \
--species homo_sapiens
