I am pretty new to bioinformatics, and just installed bash and ubuntu on my PC. When I use the 'ls' command for my home directory, it shows only a few of the files and folders. It also neglects to show my genome vcf file. Terminal also does not recognize that there is a vcf file present when i try to read it in using vcftools....I'm thinking these problems are related. I've had success on the Mac computers in my lab on campus. Please help!
