Convert GFA 2 graph segments to FASTA (two-line)

Provided by bugaco.com

Convert a GFA 2 graph segments sequence file to FASTA (two-line).

Maximum file size: 50 MB. The file is checked before conversion.

GFA 2 graph segments → FASTA (two-line)

  • Only graph segment sequences are written. Graph links and topology are not preserved.

About this conversion

The converter reads records in the input format and writes them in the output format. Data that the output format cannot store may be lost. The notes under the Convert file button list the important limits for this pair.

Run it with Biopython

For batch work, you can use Biopython's SeqIO.convert function. This pair needs no molecule type argument.

from Bio import SeqIO

count = SeqIO.convert("input.gfa2", "gfa2",
                      "output.fasta-2line", "fasta-2line")
print("Converted %i records" % count)

Samples are small illustrative files. Some come from the Biopython test suite (see the project's sample notes); they are not real study data.
