I need to use PLINK 1.07 to perform an analysis on Copy Number Variants. To my knowledge it is the only version that has implemented the CNV functions in a stable way. As I have exclusively found version 1.07 in the literature I read on CNVs analyses.

I installed version 1.07 of PLINK as I had normally done for newer versions, which I had been able to work with just fine. However, the 1.07 PLINK version doesn't work. It raises the error: "Segmentation fault (core dumped)"

I suppose this is because this version is from 2009 and was designed to work with very different computers, but I do not know how to fix this. To be more precise I tested this on two different 64-bit Windows PCs, one running Windows 10 and one running Windows 11. I used Windows Subsystems for Linux (using the latest Ubuntu distro) and I got the Linux version of PLINK from this download link: https://zzz.bwh.harvard.edu/plink/dist/plink-1.07-x86_64.zip.

Here is the exact output that I get from trying to run PLINK:

~$ plink

Please let me know what I can do to be able to run PLINK 1.07. I can provide more information if needed.

Any help or contribution will be greatly appreciated. Thank you!
