Welcome to the ascatNgs wiki!
We will aim to provide both FAQ and guides for generating custom SNP profiles on this site.
!! This package is only suitable for WGS analysis, NOT WXS (exome/pulldown) !!
Please ensure that any reference files you use have the appropriate contig naming conventions. The GRCh37 examples here do not have a chr
prefix. You can simply update the names appropriately.
Reference files for Human GRCh37 can be found here.
For Human GRCh38 the relevant reference file can be obtained as described here
There are a couple of methods available to generate the relevant SNP loci.
The pages listed here are tried and tested methods of generating SnpGcCorrections.tsv
files from public datasets. Generally these include helper scripts or commands known to work with the file format at time of creation.
- Human reference files from 1000 genomes VCFs
- Mouse reference files using Mouse Genome Project VCF files
The following page describes a generic way to create a custom SnpGcCorrections.tsv
from your own normal sample data.
If you wish the program to do automatic gender detection then specify gender loci file to option -locus
Create a species and build specific gender loci file in following format [ e.g., GRCh37d5_Y.loci]
Y 4546684
Y 2934912
Y 4550107
Y 4549638
