You can generate a letter article without uploading the original code. You can choose to put it in the appendix of the paper or not make it public at all. However, once you write it in the body of the paper, it means that the code is also a part of the body, which is equivalent to being made public to everyone. So, if your data is sensitive, write as little as possible or don't put it in the paper.

In recent years, more and more people are interested in bioinformatics, because it can publish SCI without any experiments, only relying on the relevant screening and statistical analysis of biological information.
