cusp calculates a codon usage table for one or more nucleotide coding sequences and writes the table to file.

Quick Start

To use cusp,

  1. upload your input sequence data in most format, such as fasta, GenBank, Embl, or Emsembl, gcg formats.
  2. choose your option, type in start and end sequence position
  3. launch your job

Test Data

Test data for this app can be found here: Community Data -> iplantcollaborative -> example_data -> EMBOSS


Input File
