Hello, I am starting in the xWAS (PWAS, TWAS, MWAS) field, at first I have only been using the models published by predictdb (https://predictdb.org/) on my patients summary data with predixcan (https://github.com/hakyimlab/PrediXcan). Despite this, I am trying to use more available information, for this purpose, I want to use QTL score information (for example: https://www.omicspred.org) to create models in the predixcan format so I can apply them to my data. The main problem is that I do not find information about how to use the QTL score information published by multiple authors. I would be very grateful if someone could give me some advice on this area
