The idea started as a journal club run by @siobhane13.bsky.social in September 2023 and eventually morphed into a lab wide paper at @acadresearch.bsky.social.
It was a lot of fun working with the group and co-leading with Dr. Roberta Davidson. I would love to hear your thoughts.

The necessity for authentication of ancient DNA from archaeological artefacts The study of ancient DNA (aDNA) has revolutionised the fields of archaeology, human evolution and paleoecology, offering new insights into the past. Iโ€ฆ

We review recent literature that use ancient DNA methods in the analysis of archeological artefacts. We hope this will be a useful resource to improve the inclusion of ancient DNA methods into the study of ancient artefacts.

Had a fantastic time meeting great people and learning about exciting aDNA research! Thanks @mattiassherman.bsky.social and team for organising a great event and giving me an opportunity to present my work.

Since your reads are so short, even a smaller Kmer db would struggle with classifying them. And smaller kmer db come with more false classifications as well.

Your approach is perfectly fine. You could use the classification to remove reads from taxa you are not interested in.
My opinion is that the database is more important than the classifier. If you are happy with the database, Iโ€™d stick to that.
