Question

[marwa.cs91]

Hello all, I am new in plink analysis, Conversion to plink format keeps failing due to an error.

Error: failed to open HNPGenotypes.fam

Here are the few lines of my files :

HNPGenotypes.lgen

002_S_0619 002_S_0619 200003 G G
002_S_0619 002_S_0619 200006 A A

3 rs2364379 0 192551084
1 rs2364403 0 154194376

I generated the files based on this code: https://github.com/dhibar/ADNI_Genetics_Convert_to_PLINK according to the presentation: http://www2.warwick.ac.uk/fac/sci/statistics/staff/academic-research/nichols/presentations/ohbm2014/imggen/Hibar_ImgGen-CommonVar_OHBM2014.pdf

How can I solve the error?

Thanks in advance
