 It measures the transcription level of each human transcripts ( 4-5 per genes ) in every
 31 tissues (for the V1, 50 more specific tissues for the V2).
 
-expression values are log-transformed ( x -> log(x+1) )
+The expression per tissues is the result from averaging across several patients and measurements.
 
 Each sample of the dataset correspond to:
-
 * A unique (gene_id, transcript_id) pair
-* the quantified level of expressions across several tissues
+* the quantified level of expressions across several tissues, which are log-transformed ( x -> log(x+1) )
 * the DNA sequence
 * the RNA sequence (ATCG format)
 * the protein sequence
