Build

Use the definition file to build locally:

apptainer build RNAseq.sif RNAseq.def

Tip

Use a non-interactive install by adding -y

%post
  apt-get update

  # Install less and qpdf
  apt-get install -y less
  apt-get install -y qpdf

Deploy

Pre-build image can be downloaded from the Cloud Library:

apptainer pull library://andreyhgl/singularity-r/rnaseq:latest

Tip

If apptainer/singularity is not working, try adding the remote host manually

# list the remote URI
singuliarty remote list

# add singularity cloud URI
apptainer remote add --no-login SylabsCloud cloud.sycloud.io

Execute scripts

In order to fully utilise the singularity image make sure a shebang is included in the script file #!/usr/bin/env Rscript.

#!/usr/bin/env Rscript

suppressPackageStartupMessages({
  library(edgeR)
  library(gtools)
})

...

Also make the script file executable.

chmod +x script-file.R

The singularity image expects a script file on exec.

apptainer exec library://andreyhgl/singularity-r/rnaseq:latest script-file.R
