I was reading the AlphaFold paper and had difficulty with a couple of terms introduced in the main text of the paper. I asked ChatGPT what these were but I'm not sure that it's accurate.
I had a hard time finding the definitions of an MSA (multiple sequence alignment) cluster and MSA depth. GPT-4 explains that an MSA cluster is a subset of sequences from an overall MSA that are closely related to each other, which seems to be simply the results from clustering analysis on MSA. GPT-4 also defines the MSA depth as the number of sequences in MSA. However, I want to make sure that these definitions are correct and are not just hallucinations from GPT-4.
