VCFTools - Writing 012 matrix files ... Error: Could not open temporary file.

Question

[jmounger]

Hi,

I'm trying to make a 012 matrix using VCFTools using these parameters:

--vcf /filepath/snp.vcf
--012
--out output_geno.vcf

but I keep receiving this error, and I'm not sure how to resolve the issue:

After filtering, kept 287 out of 287 Individuals Writing 012 matrix files ... Error: Could not open temporary file.

Any help is greatly appreciated!

Try increasing the size of the temporary folder

ulimit -n 3000
