Arguments

boundary_genes: a data frame of boundary gene info
region_data: a list of original region_data
region_info: a data frame of region definitions
LD_map: a data frame with filenames of LD matrices and SNP information for the regions.
snp_map: a list of data frames with SNP-to-region map for the reference.
weights: a list of preprocessed weights.
z_snp: A data frame with columns: "id", "z", giving the z-scores for SNPs.
z_gene: A data frame with columns: "id", "z", giving the z-scores for genes.
estimate_L: If TRUE, estimate L for merged regions.
expand: If TRUE, expand merged region_data with full SNPs
L: the number of effects for susie.
maxSNP: Inf or integer. Maximum number of SNPs in a region. Default is Inf, no limit. This can be useful if there are many SNPs in a region and you don't have enough memory to run the program.
LD_format: file format for LD matrix. If "custom", use a user defined LD_loader_fun() function to load LD matrix.
LD_loader_fun: a user defined function to load LD matrix when LD_format = "custom".
ncore: The number of cores used to parallelize susie over regions
verbose: If TRUE, print detail messages
logfile: The log filename. If NULL, print log info on screen.
...: Additional arguments of susie_rss.

Value

a list of merged region data, merged region info, LD_map, snp_map, and merged region IDs.
