I have downloaded this data. Now I want to find the corresponding gene expression values using R. So is there a database that I can map the ids to and get the corresponding expression values or any Bioconductor package might help me do this job.
Here's what I tried. I downloaded the median TPM by tissue count from the GTEX portal. Now used my gene names from the protein atlas dataset to search them in the GTEX dataset. For a particular gene, say BCAR3, there are expression values in TPM for different tissues. Now I am interested in kidney only. So I got the corresponding value from the GTEX dataset.
