In the example ‘Omics Biomarker Examples: “Epigenetic Clocks” in GEO Data’, several clocks such as ‘Horvath’, ‘Hannum’, and ‘PhenoAge’ are calculated. I have also tested a few others such as ‘Zhang_10’ and ‘DunedinPACE’, which all worked well.
However, ‘GrimAgeV1’ and ‘GrimAgeV2’ returned error message. Could you take a look why these two clocks do not work? Thanks!
