gff2xml
Quick Start
- Command:
gff2xml [options] < input.gff > output.xml - Local executable:
/home/vimalinx/miniforge3/envs/bio/bin/gff2xml - Full reference: See
references/help.mdfor detailed usage and options
When To Use This Tool
- Turn GFF/GFF3 feature lines into structured XML with explicit fields and parsed attributes.
- Preserve the common columns (
SeqID,Source,Type,Start,End,Score,Strand,Phase) in a machine-friendly XML layout. - Split semicolon-delimited
Attributesinto nested XML tags for downstream extraction.
Common Patterns
# 1) Convert a GFF3 file into structured XML
gff2xml < annotations.gff3 > annotations.xml
# 2) Convert and inspect parsed attributes immediately
gff2xml < annotations.gff3 | xtract -pattern GFF -element SeqID Type Start End ID Name
Recommended Workflow
- Confirm the input really is 9-column GFF/GFF3 with semicolon-delimited attributes.
- Run
gff2xmlvia stdin redirection so the wrapper can process the stream. - Inspect a few output records to confirm the expected XML tags and attribute splitting.
- Use the XML with
xtractor downstream reporting steps once the structure looks right.
Guardrails
- This is not a single binary conversion primitive; it chains
tbl2xml,xtract, andtransmute, and all of those helpers must be onPATH. - The wrapper has no real
--help/--versionpath; probing it outside a working EDirect environment mostly yields missing-command noise. - Attributes are split on semicolons into nested XML tags, so unusual attribute encodings may need spot-checking.
- Because the wrapper does not pass through positional filenames, stdin redirection is the safest invocation pattern.
