Fasta Clean

This page allows you to "clean" a fasta sequences file:

  • just put a ">" as first character of each fasta header line
  • verify that each accession number in fasta headers are correct (no space between accession number and ">", be UNIQUE, has no special characters

This tool will remove bad end of lines, empty lines, numbering, and optionally convert sequences or headers in lower or upper case.
