Dear all,
I am currently engaged in a metagenomic research project and intend to incorporate several publicly available metagenomes into my analysis alongside my own data. These publicly accessible metagenomes have been previously published. I would like to inquire whether it is necessary to seek permission from the original authors before including these metagenomes in my manuscript. Can it cause any ethical issue? Of course I will cite the paper and provide all essential information on utilized metagenomes.
Your guidance on this matter would be greatly appreciated.
