samtools in path

[jessiepelosi]

Great tool, Shelly! Thanks for putting this together. I have a very minor suggestion for the README - I struggled with getting R to recognize samtools, even with symbolically linking on HiPerGator. I found this solution online and thought it might be helpful to others:

Sys.setenv(PATH=paste("/apps/samtools/1.19.2/bin", Sys.getenv("PATH"),sep=":"))

I had put this in the beginning of the R script, so I believe it has to be called each time that the script is run.
