check_multi_rs_snp: Ensure that SNP ids don't have multiple rs ids on one line

In neurogenomics/MungeSumstats: Standardise summary statistics from GWAS

Ensure that SNP ids don't have multiple rs ids on one line

Description

Ensure that SNP ids don't have multiple rs ids on one line

Usage

check_multi_rs_snp(
  sumstats_dt,
  path,
  remove_multi_rs_snp,
  imputation_ind,
  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.
remove_multi_rs_snp	Binary Sometimes summary statistics can have multiple RSIDs on one row (i.e. related to one SNP), for example "rs5772025_rs397784053". This can cause an error so by default, the first RS ID will be kept and the rest removed e.g."rs5772025". If you want to just remove these SNPs entirely, set it to TRUE. Default is FALSE.
imputation_ind	Binary Should a column be added for each imputation step to show what SNPs have imputed values for differing fields. This includes a field denoting SNP allele flipping (flipped). On the flipped value, this denoted whether the alelles where switched based on MungeSumstats initial choice of A1, A2 from the input column headers and thus may not align with what the creator intended.Note these columns will be in the formatted summary statistics returned. Default is FALSE.
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.
