  i have ensured that the genelist that i put in was included in the train dataset (list_train_vali_Data1$Dataset1): aaaaa <- intersect(genelist,colnames(list_train_vali_Data1[[1]])) identical(aaaaa,genelist) [1] TRUE the dataset1 was established to standard as follows: ID, OS.time, OS, gene_symbols i couldnt figure out the reason that this error occurs, thank you for considering!

The error occurs in procesing your dataset2. Please check format of your Dataset2.

i have checked the format of dataset2, just same as dataset1: ID, OS_time, OS,and gene symbols. and the ML.Dev.Prog.Sig just ran well.

aaaaa <- intersect(genelist,colnames(list_train_vali_Data1[[2]])) identical(aaaaa,genelist) [1] TRUE the gene symbols in genelist were included in dataset2. i still couldnt figure it out , looking forward to your reply and thanks
