Description
Quote one GTF-style attribute value.
Genome annotations depend on coordinate origin, endpoint inclusion, strand and reading-phase conventions. A local offset or phase token can be handled precisely while a complete transcript, reference identity and biological reading frame remain separate validation questions.
Quote one GTF-style attribute value.
When to use this tool
Use GTF Escaped Quote Attribute Token when checking the stated genomic coordinate, annotation phase or attribute-value convention.
How to use the tool and how it works
- Enter value. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read quoted. Use the output convention below.
Quote one GTF-style attribute value. Reject ASCII controls 0x00..0x1f and DEL; escape backslashes first, then double quotes, and surround the result with double quotes.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| value | Value | Required. Text; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| quoted | Quoted | Required. Text; maximum UTF-16 length 8192. |
{
"input": {
"value": "alpha"
},
"output": {
"quoted": "\"alpha\""
}
}Limitations and assumptions
- This encodes one supplied value without parsing or validating a complete annotation record or selecting a dialect-specific attribute policy.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
Use the intended complete BED/GFF/GTF format, reference assembly and transcript model to validate full annotations and biological meaning.
