description: 'Track and retrieve sample locations in -80°C freezers with hierarchical

storage organization.

Trigger conditions:

- User needs to record sample storage positions (freezer ID, level, rack, box, grid

position)

- User requests to search samples by name, project, date, or location

- User requires sample inventory management and export functionality

Input: Sample metadata (name, project, quantity) and storage coordinates

Output: Structured sample location records with search and export capabilities

Success criteria:

- Accurate position recording without conflicts

- Fast search and retrieval (<1 second for 1000+ samples)

- Data integrity maintained across operations

- Export in multiple formats (JSON, CSV)

Risk level: MEDIUM (Script execution with file system access)

# Freezer Sample Locator

**Purpose**: Systematically manage and retrieve sample locations in -80°C freezers using hierarchical storage organization.

**Classification**: Tool/Script型 (本地脚本执行)

🎯 Core Functions

Primary Operations

**Record**: Store sample locations with hierarchical coordinates (freezer → level → rack → box → position)

**Retrieve**: Search samples by name, project, freezer, date, or unique ID

**Manage**: Update sample metadata, delete records, maintain inventory

**Export**: Generate reports in CSV/JSON formats with filtering options

Data Integrity Features

**Conflict Detection**: Prevent duplicate position assignments

**Validation**: Enforce proper location encoding rules

**Audit Trail**: Track creation and modification timestamps

**Backup**: JSON-based storage with automatic file creation

Data Structure

Sample location information is stored in JSON files:

{
  "samples": [
    {
      "id": "uuid",
      "name": "Sample Name",
      "project": "Project Name",
      "freezer": "F01",
      "level": 1,
      "rack": "A",
      "box": "01",
      "position": "A1",
      "quantity": 1,
      "date_stored": "2024-01-15",
      "notes": "Notes",
      "created_at": "2024-01-15T10:30:00Z",
      "updated_at": "2024-01-15T10:30:00Z"

Usage

🚀 Usage Guide

Command Line Interface

#### Sample Management

# Add new sample
python scripts/main.py add \
  --name "Sample-001" \
  --project "Project-A" \
  --freezer "F01" \
  --level 1 \
  --rack "A" \
  --box "01" \
  --position "A1" \
  --quantity 2 \
  --notes "Primary culture"

# Search operations
python scripts/main.py search --name "Sample-001"    # Name search (fuzzy)
python scripts/main.py search --project "Project-A" # Project search (exact)
python scripts/main.py search --freezer "F01"        # Freezer search
python scripts/main.py search --id "uuid-string"     # ID search (exact)

# List with optional filtering
python scripts/main.py list                           # All samples
python scripts/main.py list --freezer "F01"          # Specific freezer

# Update sample information
python scripts/main.py update --id "uuid" --position "B2" --quantity 1

# Delete sample record
python scripts/main.py delete --id "uuid"

# Export functionality
python scripts/main.py export --output samples.csv --freezer "F01"

# Statistics
python scripts/main.py stats

#### Python API Usage

from scripts.main import FreezerSampleLocator

# Initialize locator
locator = FreezerSampleLocator()

# Add sample with validation
sample = locator.add_sample(
    name="Sample-001",
    project="Project-A", 
    freezer="F01",
    level=1,
    rack="A",
    box="01",
    position="A1",
    quantity=2,
    notes="Primary culture"
)

# Search with multiple criteria
results = locator.search_samples(
    name="Sample-001",
    project="Project-A"
)

# Get formatted location
location = locator.get_sample_location(sample_id)
print(location["location_str"])  # "F01 > L1 > RA > B01 > A1"

# Export data
locator.export_csv("inventory.csv", freezer="F01")

📋 Location Encoding Standards

Hierarchical Coordinate System

|-----------|--------|-------|-------------|

| **Freezer ID** | F01, F02, F03... | F01-F99 | Physical freezer unit |

| **Level** | 1-10 | 1-10 | Vertical level (top to bottom) |

| **Rack** | A-Z | A-Z | Horizontal rack position |

| **Box** | 01-99 | 01-99 | Box number within rack |

| **Position** | A1-H12 | A1-H12 | Grid position (96-well standard) |

Validation Rules

**Uniqueness**: Each position can contain only one sample

**Format Compliance**: Strict pattern matching enforced

**Range Checking**: All components validated against allowed ranges

**Conflict Prevention**: Real-time duplicate detection

Location String Format

{Freezer} > L{Level} > R{Rack} > B{Box} > {Position}
Example: F01 > L1 > RA > B01 > A1
