APAqtls with Leafcutter

Filter dose files

I need to remove non snps and snps with <.05 from the dosage file.

I will first copy all of the dosage files to my direcory instead of changing tonys.

cp *dose.vcf.gz /project2/gilad/briana/YRI_geno_hg19/

I want to write a python script that will read in the files and perform the filters.

I wrote a python script that take in the dose file and a name of an out file. I will write a bash script to wrap this on all of the chrs.

#!/bin/bash


#SBATCH --job-name=filter_dose
#SBATCH --account=pi-yangili1
#SBATCH --time=24:00:00
#SBATCH --output=filter_dose.out
#SBATCH --error=filter_dose.err
#SBATCH --partition=broadwl
#SBATCH --mem=12G
#SBATCH --mail-type=END

module load python

do 
python filter_vcf.py chr$i.dose.vcf chr$i.dose.filt.vcf
done

Now I can use these for the fastqtl script instead.

I also updated to only use the first 2 pcs as covariates.

Run permuted version

Permutation pass to calculate correctedp-values for molecular phenotypes.

Evaluate the results

The results file has the folowing columns:

• ID of the tested molecular phenotype (in this particular case, the gene ID)
  
• Number of variants tested in cis for this phenotype
  
• MLE of the shape1 parameter of the Beta distribution
  
• MLE of the shape2 parameter of the Beta distribution
  
• Dummy [To be described later]
  
• ID of the best variant found for this molecular phenotypes (i.e. with the smallest p-value)
  
• Distance between the molecular phenotype - variant pair
  
• The nominal p-value of association that quantifies how significant from 0, the regression coefficient is
  
• The slope associated with the nominal p-value of association [only in version > v2-184]
  
• A first permutation p-value directly obtained from the permutations with the direct method. This is basically a corrected version of the nominal p-value that accounts for the fact that multiple variants are tested per molecular phenotype.
  
• A second permutation p-value obtained via beta approximation. We advice to use this one in any downstream analysis.

I can check the experiments as recomended by the FastQTL site.

Next steps:

• make plots for some of these snps

• /project2/yangili1/yangili/APAqtl/output/ceu.apaqtl.txt.gz.bh.txt (use nominal pvalue)
  
• 1. plot a qqplot with only these SNPs
     
• 2. plot a qqplot with all SNPs that you tested

Locus zoom plots to vizualize the top QTLs:

Kenneth gave me this code for making these plots. I can modify this code.

plot_locuszoom <- function(this, gen, xlim, ylim, ...)
{
  
  #this is a r object that will have the results from the fastqtl and the genotypes 
  #this$annotations has gene, snp, dist, pvalue, beta, rsid, chr, pos, bpval, and other extra annotations about the snps
  rbPal <- colorRampPalette(c('lightblue','blue','purple','red'))(101)
  cols <- c()
  
  # gotta figure out how everythign correlates with this snp
  # row <- which(this$annotations$rsid==snp)
  # gen <- as.numeric(this$genotypes[row,10:129])
  nrow <- nrow(this$annotations)
  cors <- sapply(1:nrow, function(j) cor(gen, as.numeric(this$genotypes[j,10:33])))
  
  cols <- c()
  for (j in 1:nrow) cols[j] <- rbPal[round(100*(cors[j])^2)+1]
  
  plot.new()
  plot.window(xlim=xlim, ylim=ylim, xlab='position', ylab='-log10(p-value)', ...)

 
  points(x=this$annotations$pos, y=-log(this$annotations$bpval,10), pch=19, col=cols)
  axis(2)
  box()
  mtext('-log10(p-value)', side=2, line=2, cex=0.7)
}

I will try this with the top total snp first. It is in chrom15, the snip id is 15:76191353. I want to pull genotypes for snp within 50000 bases (window size).

I can write a python script that takes a snp position and filters only the snps 25000 up and 25000 downstream of this snp. I can subset just the individuals in the sample list once i move this into R.

Need to make sure to unzip the specfici vcf file first.

I actually need to do this with the nominal snps.

The most sig. in the nominal total is 4:186328829:186328922:NM_018359.3_-_peak260565, 4:186325141

I want to run the python genotype filter.

Generally I will need to grep the correct line from the geno and pheno file then make the plot like this.

Next I will run for the top Nuc QTL.
