Input Schema

The original structured input schema is retained conceptually. Use the SKILL section below for executable instructions.

SKILL

SKILL: Bioinformatics Format Converter

Name

Bioinformatics Format Converter

Description

Converts common bioinformatics file formats, supporting conversion between FASTA, GenBank, FASTQ, PDB, CSV, TSV and other formats.

Input

source_file: Source file path (string, required)
target_format: Target format (string, required)
options: Additional options (object, optional)
- quality_threshold: FASTQ quality filter threshold (int, default: 20)
- compression: Output compression option (boolean, default: false)

Supported Formats

Source Format	Target Format	Description
FASTA	GenBank	DNA/protein sequence conversion
GenBank	FASTA	Sequence extraction
FASTQ	FASTA	Conversion after quality filtering
FASTQ	FASTQ	Quality filtering
PDB	MMTF	Structure format compression
CSV	TSV	Delimiter conversion
TSV	CSV	Delimiter conversion

Execution Steps

Step 1: Detect Input File Format

1. Read file header
2. Identify format based on characteristics:
   - FASTA: Starts with ">"
   - GenBank: Contains "LOCUS" keyword
   - FASTQ: Starts with "@", each record is 4 lines
   - PDB: Starts with "HEADER" or "ATOM"
   - CSV/TSV: Detect delimiter

Step 2: Parse File Content

1. Use BioPython or standard library for parsing
2. Extract sequence/structure/table data
3. Validate data integrity

Step 3: Convert to Target Format

1. Construct output based on target format
2. Apply any specified options
3. Handle special characters and format requirements

Step 4: Output Converted File

1. Write to target file
2. Return output path and statistics

Output

{
  "success": true,
  "output_file": "path/to/output.file",
  "input_format": "fasta",
  "output_format": "genbank",
  "records_processed": 5,
  "statistics": {
    "total_bases": 1500,
    "total_sequences": 5
  }
}

Error Handling

File not found: Return error code FILE_NOT_FOUND
Format not supported: Return error code UNSUPPORTED_FORMAT
Parsing failed: Return error code PARSE_ERROR
Invalid input: Return error code INVALID_INPUT

Tools

biopython: Biological sequence and structure file parsing
python standard library: CSV/TSV conversion, file operations

This is a formatting cleanup revision. It does not introduce a new scientific claim.

## Description
Converts common bioinformatics file formats, supporting conversion between FASTA, GenBank, FASTQ, PDB, CSV, TSV and other formats.

## Input
- `source_file`: Source file path (string, required)
- `target_format`: Target format (string, required)
- `options`: Additional options (object, optional)
  - `quality_threshold`: FASTQ quality filter threshold (int, default: 20)
  - `compression`: Output compression option (boolean, default: false)

## Supported Formats

| Source Format | Target Format | Description |
|---------------|--------------|-------------|
| FASTA | GenBank | DNA/protein sequence conversion |
| GenBank | FASTA | Sequence extraction |
| FASTQ | FASTA | Conversion after quality filtering |
| FASTQ | FASTQ | Quality filtering |
| PDB | MMTF | Structure format compression |
| CSV | TSV | Delimiter conversion |
| TSV | CSV | Delimiter conversion |

## Execution Steps

### Step 1: Detect Input File Format
```
1. Read file header
2. Identify format based on characteristics:
   - FASTA: Starts with ">"
   - GenBank: Contains "LOCUS" keyword

3. Handle special characters and format requirements
```

### Step 4: Output Converted File
```
1. Write to target file
2. Return output path and statistics
```

## Output
```json
{
  "success": true,
  "output_file": "path/to/output.file",
  "input_format": "fasta",
  "output_format": "genbank",
  "records_processed": 5,
  "statistics": {
    "total_bases": 1500,
    "total_sequences": 5
  }
}
```

## Error Handling
- File not found: Return error code `FILE_NOT_FOUND`
- Format not supported: Return error code `UNSUPPORTED_FORMAT`
- Parsing failed: Return error code `PARSE_ERROR`
- Invalid input: Return error code `INVALID_INPUT`

## Tools
- **biopython**: Biological sequence and structure file parsing
- **python standard library**: CSV/TSV conversion, file operations
