Welcome to the focus wiki!
Here you'll find details on how to import weights, train weights using your own data, clean summary GWAS, and perform fine-mapping on TWAS results.
Please see the sidebar for links to each.
We recommend using reference LD from LDSC. From the command line this can be done as
wget https://data.broadinstitute.org/alkesgroup/LDSCORE/1000G_Phase3_plinkfiles.tgz
tar -xvzf 1000G_Phase3_plinkfiles.tgz
We recommend using a multiple tissue, multiple eQTL reference panel weight database here. This combines GTExv7 weights from PrediXcan with METSIM, NTR, YFS, and CMC weights from FUSION software into a single usable database for FOCUS.
