Uncompress The 1001 Genome vcf.gz

Question

[sarah.k]

Hi everybody. Is there any Linux command to uncompress .vcf.gz format. I ma using windows winrar at the moment but it's too slow. Many thanks.

What would you do knowing linux command, if you are using windows? What are you planning to do with the file? You may not need to uncompress it.

[sarah.k]

I want to import it to a NoSQL database such as Apache Cassandra on my Linux machine. But I can't find a way to uncompress it. So, I've decided to uncompress it in windows then move the .vcf file on my Linux machine.

curious ; why ?

why don't you move the *.vcf.gz on linux before uncompressing it with gunzip ?

[sarah.k]

for your first question: looking for new database generation for restore and retrieval genomic data and its data modeling. for your second question: I have my data on Linux machine too. what is gunzip? Do you have an example of using it to decompress .vcf.gz file?

[Pierre Lindenbaum]

what is gunzip?

https://linux.die.net/man/1/gzip

gunzip file.vcf.gz

I've also used your vcf2sql script. But it didn't work for my data.

Without the command used, the exact error message, and / or a sample of the data, no one can possibly help you.

[shawn]

which dataset do you use? There are many vcf files. I do not know which one is used for gwas analysis. Thanks.

gunzip

most commands in linux have gzip compressed file support versions. For example zcat, zmore, zgrep... Most bioinformatics tools support gzip-compressed files, for example: vcftools --gzvcf your.vcf.gz
