Many thanks for the response, truly appreciate it!
As you suggested, I did contact the admin of the cluster in order to install that module.
However, as GenoMax mentioned, I also suspect that the bioinfo-tools is a sort of catch-all name for several bioinformatics programs. Therefore, while waiting for reply from my cluster admin, I tried to search the web to find out which programs are included within this module, but unfortunately found only few scripts that use it, without any further explanation about what it is or what it includes. Would love to hear if you have any suggestions for finding any additional information in that case.
Thanks again!
