Я пытаюсь загрузить данные TCGA, но получаю эту ошибку:
Ошибка в summazeMaf (maf = maf, anno = clinicData, chatty = verbose): столбец Tumor_Sample_Barcode не найден в предоставленном клинические данные. При необходимости переименуйте столбец, содержащий имена образцов, в Tumor_Sample_Barcode.
Это мой код:

library(maftools)

survival_data <- as_tibble(clinical[,c("days_to_last_followup","days_to_death","vital_status","bcr_patient_barcode","patient_id")])

survival_data <- filter(survival_data,!is.na(days_to_last_followup)|days_to_last_followup>0 &is.na(days_to_death)|days_to_death > 0 ) #ensuring positive values
