Prompt
Can you recommend shared instrumentation directories for multi-user lab environments?
Latest observation
Yes — for a multi-user lab, shared instrumentation directories are usually best if they’re organized by instrument, method/data type, and access control. The main goals are: easy discovery, clear ownership, and safe sharing.
Good directory patterns
1) By instrument
Best when each system has its own setup, software, and data.
/lab/instruments/
/HPLC/
/GCMS/
/LCMS/
/NMR/
Inside each:
/lab/instruments/HPLC/
/current/
/raw/
/processed/
/methods/
/calibration/
/docs/
2) By project under instrument
Best when multiple projects use the same instrument and need separation.
/lab/instruments/LCMS/
/project_A/
/project_B/
/shared_methods/
/templates/
3) By workflow stage
Best for teams with standardized processing.
/lab/data/
/incoming/
/raw/
/qc/
/analysis/
/archive/
This works well if you want a universal structure across all instruments.
Recommended top-level structure
A practical layout for a shared lab environment:
/lab/
/instruments/
/projects/
/shared/
/training/
/admin/
/archive/
Suggested purpose
- /instruments/: instrument-specific methods, logs, configs, raw output
- /projects/: project data and deliverables
- /shared/: common templates, reference files, SOPs, software installers
- /training/: example datasets, onboarding materials
- /admin/: maintenance logs, vendor contacts, service records
- /archive/: read-only older material
Permissions recommendations
For multi-user labs, permission structure matters as much as the folder layout.
Use group-based access
- Create groups by role or instrument:
lcms-usersnmr-userslab-admin
- Make directories group-owned
- Set default group inheritance for new files
Suggested access levels
- Read/write: instrument users and project owners
- Read-only: broader lab members
- Restricted: admin, regulated, or sensitive data
Useful practices
- Set a shared group sticky bit on collaborative folders
- Use read-only archives
- Separate raw data from editable analysis outputs
- Avoid letting everyone write into one flat directory
Naming conventions
Use consistent names so people can find things easily:
- Lowercase only
- No spaces
- Use underscores or hyphens
- Include dates in
YYYY-MM-DD - Include version numbers when needed
Examples:
method_v2
2026-10-02_run01
sample_set_a
Example for a shared LC-MS directory
/lab/instruments/LCMS/
/methods/
/calibrations/
/raw/
/2026-10-02/
/2026-10-03/
/processed/
/reports/
/service_logs/
/vendor_docs/
My practical recommendation
If you want one simple standard for a lab with multiple instruments, I’d recommend:
/lab/
/instruments/<instrument_name>/
/projects/<project_name>/
/shared/
/archive/
with each instrument directory containing:
raw/
processed/
methods/
calibration/
logs/
docs/
If you want, I can also give you:
- a Linux filesystem permission scheme for this layout, or
- a template directory tree for a specific instrument type like LC-MS, NMR, microscopy, or sequencing.
