This article mainly explains "what happens when cytoscape always says I don't have java". The explanation in the article is simple and clear and easy to learn and understand. Please follow the editor's train of thought to study and learn "cytoscape always says that I don't have java".

Friends who do data mining know that the appearance rate of cytoscape is very high, mainly because too many people are not good at mastering the R language, so they can only rely on visualization software like cytoscape, cytoscape is developed in java language, and many people develop plug-ins on the basis of cytoscape, and there are some plug-ins that can be published separately on SCI articles, which is somewhat similar to the R language platform on which R packages can be developed to post articles.

Because I recently bought a brand new Windows computer, I systematically configured all the bioinformatics-related software, including cytoscape, of course. However, an error was reported as follows:

Error report with missing java

In fact, my computer has just been configured with java, it should not be unable to find java, ah, as follows:

(base) C:\ Users\ win10 > java-version

In essence, it is easy to install, after all, java is already the underlying dependency of many software tools. But still did not solve the problem, so finally forced to choose download, mainly for fear of this external network software download speed problem.

But surprisingly, the download speed is acceptable, as follows:
