db files are in sqlite format and contain weights to calculate genetic predictors of gene expression Blood, Liver indicate the tissue where the RNA was extracted from Crohns and LDL indicate that prediction models were generated using SNPs available in the GWAS summary results used in the paper (Wainberg et al https://doi.org/10.1038/s41588-019-0385-z) *txt.gz filex contain covariances between SNPs needed to run the summary version of PrediXcan or other TWAS methods Information about the RNAseq data can be found here https://pubmed.ncbi.nlm.nih.gov/27540175/ Sample size n=522
