If you want to use the MetaXcan suite of tools, you will need to format your prediction weights in sqlite format.
Find a sample script that formats FUSION weights to predictdb format here
If you want to use the summary version of PrediXcan, you will also need the covariances between SNPs Fine a sample script here
