    Vcftools to convert vcf to plink, help

    I have been trying to use vcftools to convert a vcf file into plink ped and map files.

    If I separate my vcf by chromosome, then the it works. If I leave it as a whole file, it appears to run fine, but when I use the converted files with plink, I receive the following error:

    ERROR:
    A problem with line 1 in [ 25215.ped ]
    Expecting 6 + 2 * 87492462 = 174984930 columns, but found 104052725


    Any idea why this is, or how to fix it?
    Thanks!

    by seqadmin


    Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...
