 In protein sequences—as there are 61 sense codons but only 20 standard amino acids—most amino acids are encoded by more than one codon. Although such synonymous codons do not alter the encoded amino acid sequence, their selection can dramatically affect the production of the resulting protein. Codon optimization of synthetic DNA sequences for maximum expression is an important segment of heterologous expression. However, existing solutions are primarily based on choosing high-frequency codons only, neglecting the important effects of rare codons. In this paper, we propose a novel recurrent-neural-network (RNN) based codon optimization tool, ICOR, that aims to learn codon usage bias on a genomic dataset of Escherichia coli. We compile a dataset of over 42,000 non-redundant, robust genes that are used for deep learning. The model uses a bidirectional long short-term memory-based architecture, allowing for the sequential information of genes to be learnt. Our tool can predict synonymous codons for synthetic genes towards optimal expression in E. coli. We demonstrate that sequential context achieved via RNN may yield codon selection that is more similar to the host genome, therefore improving protein expression more than frequency-based approaches. On a benchmark set of over 40 select DNA sequences, ICOR tool improved the codon adaptation index by 41.69% compared to the original sequence. Our resulting algorithm is provided as an open-source software package along with the benchmark set of sequences.
 
 ### Quickstart
-I really like having a quickstart section that gives me a single command to install prereqs, a single command to run all tests (if any), and a single command to run the application. Something like:
+Quickstart to run install prerequisites and then launch the ICOR optimization script.
 
 ```bash
 # Install prereqs
