GTEx data

data = readRDS('../data/MatrixEQTLSumStats.Portable.Z.rds')
Z = data$test.z

Flash:

flash.data = flash_set_data(Z)
f_greedy = flash_add_greedy(flash.data, K=30)
f_b = flash_backfit(flash.data, f_greedy)

saveRDS(list(backfit = f_b, greedy = f_greedy), '../output/GTExVarCol.rds')

Flash again on the loading matrix

flash.loading = flash_set_data(flash_get_ldf(f_b)$l[,1:23])
fl_greedy = flash_add_greedy(flash.loading, K=30)
fl_b = flash_backfit(flash.loading, fl_greedy)
saveRDS(list(backfit = fl_b, greedy = fl_greedy), '../output/GTExVarColLoaing_Flash.rds')
