check_frq: Ensure all SNPs have frq score above threshold

In neurogenomics/MungeSumstats: Standardise summary statistics from GWAS

Ensure all SNPs have frq score above threshold

Description

Ensure all SNPs have frq score above threshold

Usage

check_frq(
  sumstats_dt,
  path,
  FRQ_filter,
  log_folder_ind,
  check_save_out,
  tabix_index,
  nThread,
  log_files
)

Arguments

path	Filepath for the summary statistics file to be formatted. A dataframe or datatable of the summary statistics file can also be passed directly to MungeSumstats using the path parameter.
FRQ_filter	numeric The minimum value permissible of the frequency(FRQ) of the SNP (i.e. Allele Frequency (AF)) (if present in sumstats file). By default no filtering is done, i.e. value of 0.
log_folder_ind	Binary Should log files be stored containing all filtered out SNPs (separate file per filter). The data is outputted in the same format specified for the resulting sumstats file. The only exception to this rule is if output is vcf, then log file saved as .tsv.gz. Default is FALSE.
tabix_index	Index the formatted summary statistics with tabix for fast querying.
nThread	Number of threads to use for parallel processes.
log_files	list of log file locations

Value

list containing sumstats_dt, the modified summary statistics data table object and the log file list
