Create input datasets for mamba() function and clumping
Take gwas summary stat files, do ivw-meta-analysis, create an assoc dataset which could be used for clumping association statistics in plink, create beta and s2 input datasets for mamba() model

summary_files |
A list of summary statistic files with common column names |
standardize_beta_and_s2_datasets |
in the outputted b and s2 data tables, do you want the effect size estimates and variances standardized (i.e. beta = beta_k*sqrt(2*af_k*(1-af_k)))? Default is TRUE. |
beta_name |
name of effect size estimate column |
s2_name |
name of effect size variance estimate column |
n_name |
name of n column |
af_name |
name of af column |
ref_name |
name of reference allele column |
alt_name |
name of alt allele column |
chr_name |
name of chr column |
bp_name |
name of bp column |
a list of three data.tables (beta, s2, and assoc)
