Can you recommend shared instrumentation directories for multi-user lab environments?

Yes — for a multi-user lab, you generally want shared instrument directories that are:

• accessible by all authorized users
• protected from accidental deletion/modification
• easy to back up
• organized by instrument, method, or project
• separate from personal home directories

Good directory patterns

1. One top-level shared lab area

A common approach is:

/shared/lab/

or

/data/lab/

Then organize by function:

/shared/lab/instruments/
    instrument_a/
    instrument_b/
    instrument_c/

This works well if multiple instruments and teams need a common location.

2. Instrument-specific directories

For each device, use a stable structure like:

/shared/lab/instruments/LCMS01/
    raw/
    processed/
    methods/
    calibrations/
    qc/
    logs/

This is a good default for most labs because it keeps data, methods, and logs together.

3. Separate “shared” from “user”

A useful convention is:

/shared/lab/            # shared, controlled by lab admins
/home/<user>/           # private user space
/project/<project>/     # project-specific collaboration

That way instrument data stays in a managed space, while users keep drafts and personal files elsewhere.

Recommended layout for each instrument

A practical template:

/shared/lab/instruments/INSTRUMENT_NAME/
    acquisition/
    raw/
    processed/
    methods/
    templates/
    reference/
    logs/
    maintenance/
    exports/

Typical meanings

• acquisition: current run files being collected
• raw: immutable original data
• processed: analyzed or converted data
• methods: instrument methods/protocols
• templates: standard sequences, report templates
• reference: standards, lookup tables, libraries
• logs: run logs, audit notes, troubleshooting
• maintenance: service records, calibration
• exports: data sent to other systems/users

Best practices for shared lab directories

Permissions

• Give users read access broadly
• Limit write access to designated groups
• Keep a lab-admin or instrument-admin group for maintenance
• Use group ownership and umask policies to prevent permission problems

Protect raw data

Make raw data:

• read-only after acquisition, if possible
• stored separately from editable folders
• versioned or timestamped

Example:

raw/2026-07-31_run01/
raw/2026-07-31_run02/

Use consistent naming

Avoid spaces and special characters. Prefer:

2026-07-31_sampleA_rep1.raw

instead of:

Sample A - Rep 1 final v2!!

Backups

Put shared instrument data on storage that is:

• backed up automatically
• monitored for quota and disk usage
• accessible even if one workstation fails

Auditability

If the lab is regulated or needs traceability:

• keep logs
• avoid overwriting raw files
• use timestamps and run IDs
• consider read-only archive directories

Example directory recommendation

If you want a simple and effective standard:

/data/lab/
    instruments/
        GCMS01/
            raw/
            methods/
            logs/
            qc/
            archive/
        HPLC02/
            raw/
            methods/
            logs/
            qc/
            archive/
    projects/
    admin/

If you want a stronger policy-based structure

You could use:

/data/lab/
    shared-read/
    shared-write/
    instruments/
    projects/
    archive/
    admin-only/

This can help enforce who can edit what.

If you want, I can also suggest:

1. a Linux permissions model for shared lab directories, or
2. a folder template for a specific instrument type like LC-MS, NMR, microscopy, or sequencing.
