Manual changes to PLINK genotype files

I show here how to do manually remove individuals or SNPs from #PLINK #genotype files. As I underline in the video, it is generally not recommended to do manual edits, but I thought it is better to have some info out there, to do it with relative safety, as opposed to wild experimentatino that leads to errors.

Hi!! Is there a way to transform a ped file to csv in plink?

Hi,
I think not in PLINK, but you just need to replace the space delimiters wit commas, and you are done. Any environment and approach could be used. R is my favorite of yourse, but gets tricky quickly with large files. In general the Linux command line tools are the most efficient for something like this.
