Hello all,

I'm using genegeneinter package for epistasis analysis. I head into below error while creating initial data object:

Error in snpStats::read.pedfile(file = file, ...) : 
No unambiguous snp names found on file
In addition: Warning message:
In if (length(line) == 0) break :
closing unused connection 4 (format_normal.ped)

Code:

pedF <- "format_normal.ped"
infoF <- "snp_chr.info"
posiF <- "gene_snp_chr_pos.txt"
data.importedF <- importFile(file=pedF, snps=infoF, pos=posiF, pos.sep="\t")

244229 snps in .map file, 1468 individuals in .fam file.

Versions: GeneGeneInteR_1.2.0 

R version 3.4.2 (2017-09-28)
Platform: x86_64-w64-mingw32/x64 (64-bit)

snpStats_1.26.0

Don't know what's wrong in these four lines. Any guidance would be much appreciated. Thanks!! 

My data are in format as provided in examples. tab delimited and such for .ped file.
