Hi everyone,
Thank you all for your replies, we really appreciate your cooperation. Below is a summary of the tools and data sets recommended by Torsten, Andrew, paolo, and emijrp. We would also like to know if there is any existing Wikipedia page that includes such a list so we can add to it. Otherwise, where do you suggest adding this list so it is noticeable and useful for the community?
