This dataset describes transcript expression levels based on the data
from [GTEX](https://gtexportal.org/home/downloads/adult-gtex/bulk_tissue_expression) (
file: GTEx_Analysis_2017-06-05_v8_RSEMv1.3.0_transcript_tpm.gct.gz )

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).

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, which are log-transformed ( x -> log(x+1) )
* the DNA sequence
* the RNA sequence (ATCG format)
* the protein sequence

### NOTE

Only coding genes are included at the moment, there there the RNA is actually mRNA
