CatDCD

This software is called CatDCD, and it works similarly to the Unix command "cat." Essentially, it combines multiple DCD files into a single DCD file. However, it also offers additional functionality. You can use CatDCD to selectively choose which atoms to include in the final DCD file. Additionally, users can specify which frames to include or exclude. This means that CatDCD can both merge and split DCD files, providing ultimate flexibility for data manipulation. Overall, CatDCD is a powerful tool for anyone who works with DCD files and wants more control over their data.
