A Letter to the Editor generally takes one of the following forms:

• A substantial re-analysis of a previously published article in Journal of Cheminformatics or in another journal.

• An article that raises issues of general interest to the broad readership of Journal of Cheminformatics.

The abstract should be a short, unstructured, single paragraph summary, no more than 100 words, of the major points raised, making evident the key work highlighted in the article. Please do not use abbreviations or references in the abstract.

Letters to the Editor should be between 300–800 words and may contain one figure.

Letters to the Editor may be subject to peer review at the editors’ discretion.
