Computational Fluid Dynamics (in graphics mostly)

Disclaimer: I have no professional education in Compulational Fluid Dynamics, these are various notes on what I found/learned when trying to learn a bit on the topic. Some of the notes lack sources as I wrote them up later often just remembering some StackExchange answer. Some things I might have misinterpreted.

It's a list of directories that tell your operating system where to look for programs, so that you can just write script instead of /home/me/bin/script or C:\Users\Me\bin\script. But different operating systems have different ways to add a new directory to it:

Windows

The first step depends which version of Windows you're using:

If you're using Windows 8 or 10, press the Windows key, then search for and

	*Filter variants per region (in this example, print out only variants mapped to chr1 and chr2)
	qbcftools filter -r1,2 ALL.chip.omni_broad_sanger_combined.20140818.snps.genotypes.hg38.vcf.gz

	*printing out info for only 2 samples:
	bcftools view -s NA20818,NA20819 filename.vcf.gz

	*printing stats only for variants passing the filter:
	bcftools view -f PASS filename.vcf.gz
