Thank you Ram for your reply. I managed to build the docker image, as you suggest.
I suppose I need to run one of the scripts in the folder:
/xchip/tcga/Tools/absolute/releases/v1.5/run
However, there are 8 scripts in the directory and I'm not sure who does what and which one to start with
For example:
Rscript "/xchip/tcga/Tools/absolute/releases/v1.5/run/ABSOLUTE_cli_start.R" --help
remains rather limited in its documentation
