Also, these three belong together, and while individual files alone could give you some information, all three are needed to analyze the data.ДЄ quick note here: technically it is possible to use any file name with the right options, but why would you complicate your life (also) with this? So I really suggest sticking to this naming convention, i.e. What I mean is that the file extensions are not just some random names, but pre-defined ones from PLINK. The second thing is maybe not so apparent, but once you have seen a few data sets, it will become obvious.

When you use the correct option in PLINK, you can refer to all three files just by using this common name, in this case, ADAPTmap_genotypeTOP_20160222_full. The first one is that all three files have exactly the same name, and differing only in the file extension. Just by looking at the file names, you can see some special characteristics. This is one of the most standard formats of the data that is efficient for computation and storage space. The three files contain information on animals, SNP positions, and animals in a so-called PLINK 'binary ped' format. You should see something like this:ДЇigure 6.1: The AdaptMap goat genotype files in PLINK format

In this post, you will see how the genomic data looks like in a PLINK format, and how to tell its basic characteristics just by looking at it. This particular data set is linked to the publication Bertolini et al. For this introduction and also the follow-up demonstrations we will use the AdaptMap goat data set. The good news is that due to journal and funding agency policies, and the general goodwill of various research teams there is a lot of SNP data available. You only need one more thing, and that is the data. In case you read this book from the beginning, you now have a good plan where to place your files and the support programs installed. Learning outcomes At the end of this chapter, you will be able to recognize and describe the format of SNP genotype files.
