QCTOOL 2.0-rc8

QCTOOL is a command-line utility program for basic quality control of gwas datasets. It supports the same file formats used by the WTCCC studies, as well as the binary file format described here and the Variant Call Format, and is designed to work seamlessly with SNPTEST and related tools. A typical use of QCTOOL is to compute per-sample and per-SNP summary statistics for a cohort, and use these to filter out samples and SNPs (either by removing them from the files or by writing exclusion lists). QCTOOL can also be used to perform various subsetting and merging operations, and to manipulate sample information in preparation for association testing - as shown on the examples page.

Accessing the software

To load the module:

$ module load QCTOOL/v2.0-rc8-iomkl-2018a
