Here I have clinical data which each line is a case, its number is TCGA-xxxx-xx(only three fields，such as TCGA-A6-2670).
But the expression data have multiple samples of a case (such as TCGA-A6-2670-01A-02R-0821-07, TCGA-A6-2670-01A-02D-0820-05, TCGA-A6-2670-01A-02T-0822-13 and so on)？
So how can I match every sample to the only one clinical record. Or do all cancer samples correspond to the same clinical case？
(I have checked the clinical data, there's no information can match the sample)
Thank You Very Much！
