Columns in the file:
MarkerName - unique marker identification across input files
Chromosome - chromosome of marker
Position - physical position in chromosome of marker
EA - allele, which effect was measured across input files
NEA - other allele
EAF - average effect allele frequency (weighted by the samplesize of each input file)
Nsample - total number of samples
Ncohort - total number of cohorts, where the marker was present
Effects - effect direction across cohorts (+ if the effect allele effect was positive, - if negative, 0 if the effect was zero, ? if marker was not available in cohort)
