View source for CryoNAV Sample Experiment Management

CryoNAV organizes cryo-ET experiments around a hierarchical data model (see [[CryoNAV Data Lifecycle|CryoEM Data Lifecycle]] for the full hierarchy). The Sample & Experiment Management area of the interface covers the day-to-day operations on these entities: creating projects, importing grids, linking FIB-SEM images, and assigning roles.

== Projects, grids, and team membership ==

Projects group related experiments. Each project contains one or more grids; each grid contains search maps and tilt series. Project owners invite team members and assign roles:

* '''System Administrator''' -- manages the deployment.
* '''Project Owner''' -- manages membership and access for one or more projects.
* '''Editor''' -- can submit jobs and edit data within assigned projects.
* '''Viewer''' -- read-only access.

Multiple owners may be assigned per project, and ownership can be transferred.

== Cryo-FIB sample preparation records ==

For workflows that involve cryo-focused ion beam milling, FIB-SEM images can be attached to the corresponding grid entity (overview images, milling progress snapshots, final lamella views). These images are linked to the lamellae as they appear in the TEM atlas and search maps, providing a single location where the full life of a grid -- from FIB preparation through tomogram -- can be reviewed.

== Rating and tagging tilt series ==

Each tilt series can be rated on a 1-to-5 star scale and assigned arbitrary text tags. CryoNAV suggests common tags (''good-ctf'', ''bad-ice'', ''thick-ice'', ''contamination'', ''promising'', ''priority'', ''exclude'') but the vocabulary is open, so each lab can develop its own conventions. Tags are color-coded for visual distinction. Combined filter expressions allow batch selection by rating and tag (e.g., "rating &gt;= 4 AND NOT tagged 'bad-ice'").
