[Pierre Lindenbaum]

no one will answer because no one knows what's in SNP.txt

[Nai]

Sorry, Here SNP.txt is converted .vcf file for MatrixEQTL. The format is: id Genotype1 Genotype2 Genotype3 Genotype4 Genotype5 Genotype6 rs1457723673 1 1 1 1 1 1 1 1 2 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 rs779258992 1 1 2 2 1 1 1 1 2 1 1 1 2 1 3 1 2 1 1 1 1 1 1 1 1 1 3 1 rs1366371903 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 0 1 1 1 1 0 1 0 1 1 1 1 0 1 0 1 1 1 rs150969722 1 1 1 1 1 3 0 1 0 0 0 0 0 0 1 1 0 1 1 0 0 1 1 1 1 1 1 1 1 1 0 0 1 1 0 0 rs1351390918 1 1 1 1 1 1 1 1 1 0 1 1 1 0 2 1 1 1 1 1 1 1 1 1 1 1 0 1 1 1 0 0 1 1 1 rs1363828207 1 1 1 1 3 1 1 1 1 0 1 0 1 0 1 1 1 1 0 1 0 1 1 1 1 1 1 1 1 1 1 0 1 1 1 . 1 1 1 1 1 1 1 1 1 0 1 1 1 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2 1 1 1 1 1 1 1 1 1 1 1 1 1 . 1 1 1 1 1 1 2 1 1 0 1 1 1 1 1 2 1 1 1 1 1 1 1 1 1 1 1 1 1 2 1 1 1 3 1 1 1 1 1 1 1 1 1 . 1 1 1 1 0 1 1 1 1 2 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2 1 1 1 1 1 1 1 1 1 1 1 1 1 . 1 1 1 1 1 1 1 3 1 1 1 1 1 1 2 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2 1 1 1 1 1 1 1 1 1 1 1 1 1

These dots which don't have SNPid I want to replace as Chromosomal Position

[Pierre Lindenbaum]

get a file rs# CHROM:POS and use join to merge both files. https://linuxconfig.org/join

[Nai]

I don't have this file rs #CHROM:POS

[Nai]

I don't have this file rs #CHROM:POS which is related to my SNP.txt
