OK, so you are going to need to [get a bit friendly with unix](https://www.dummies.com/computers/operating-systems/unix/) because the Iridis service runs unix (linux). In general you will be interacting with it using a command line tool like terminal/console etc. Back to the good old days.
You can, possibly, get iridis to open an Xwindow on your PC nut that requires fancy ssh tunneling and stuff.

## Now what?
You can interactively run R scripts by running R. Or you can run them non-interactively using the Rscript <yourScript.R> command. But you probably shouldn't.
You should submit your commands (e.g. `Rscript myScript.R`) to the Iridis scheduling system so it can balance everyone's needs. You need to [learn how to do this](https://hpc.soton.ac.uk/redmine/projects/iridis-4-support/wiki/Job_submission)...
## How to get your code on Iridis
If you've set up a repo on git.soton it's easy - Iridis has git installed. You will have to use git at the command line but it's [not so bad](https://docs.gitlab.com/ee/gitlab-basics/start-using-git.html)...
If you haven't then do so.
## Where to put your data
Sadly Iridis cannot see `J:\ or \\soton.ac.uk\resource\` so you you can't follow [usual advice](https://git.soton.ac.uk/SERG/workflow/-/blob/master/howTo/keepingData.md). You will need to copy the data you need to your home directory on Iridis. Do this using sftp - [CyberDuck](https://cyberduck.io/) works well on OSX, no doubt there are others for [Windoze](https://hpc.soton.ac.uk/redmine/projects/iridis-4-support/wiki/Transferring_files_to_and_from_Iridis_4).
If you [run out of space](https://hpc.soton.ac.uk/redmine/projects/iridis-4-support/wiki/User_account_information_and_limits) in your home folder/directory (100 GB max) you can also put it in a scratch folder which will take 1 TB. But this is not backed-up - so data in there is at risk.
## What you cannot do
Run RStudio. Well OK, you can. But it needs the ssh tunneling and XWindow thing mentioned above. Yeahnah.
