20 Project code handoff checks

At some point, it might be time for you to move on to a different opportunity. We will miss you! But before you go, there are some things we should check, to make sure we understand the code and files in the project(s) you were working on.

• Is the code version controlled?
• Is the home directory on JHPCE listed on the main README.md?
• Do we have write access to these files? Check with nfs4_getfacl and/or ls -lah.
• Is there a clean git status output?
• Are the files organized as specified in “Organizing your work”?
• If not, is there one or more README.md files explaining how the files are organized and which code was run first, then second, etc?
• Is there sessioninfo::session_info() output on the log files or commented on the R scripts? This is useful for reproducibility and for writing the methods sections of papers.
• Check if any of the packages were installed from GitHub. If so, ask why GitHub versions were needed. For example, harmony/issues/145. Note this on the README.md or as a comment on the top of the script.
• Are the scripts linear? That is, can they be re-run from line 1 till the end linearly?
• Do we know how much RAM or how many cores are required for each script?
• Ideally: This can be well documented with the companion shell scripts.
• Less ideal but still good: code comments noting the qrsh / qsub commands used.
• Do we know about any JHPCE modules that need to be loaded for running these scripts?
• Ideally: this can be documented on the companion shell scripts.
• Do the scripts have comments?
• Do we know which script was used for making each plot or output file?
• Sometimes plot names have been duplicated across scripts, leading to ambiguity on which script made which plot.
• Was here::here() used?
• If not, do we have access to the full paths used?
• Is there any raw-data that should be backed up that is not backed up right now?
• Make a list of the main software used and highlight any software that is new to us, in case we need to check more about it before the author of the code leaves.
• Someone with familiarity of the biological context (e.g. single-cell cell types), does the code make sense?
