You can't just liftover from one build to another using only coordinates correct?
... Lets say I have (dumb example) CHROM POS REF ALT 1 1 A T Say this site is hg19 and Ref allele is referring the forward strand and maps to position 100 on hg38. You can just blindly update the position like this correct? CHROM POS REF ALT 1 100 A ...

what does it mean when a plink bim file contains '*' as an allele
... I have a bim file that has lines like this `6 rs563372567 0 33966734 * G` does this just mean "not G" at a multiallelic site? Or a single nucleotide deletion perhaps (in this case deletion of G)? ...

Is there a reason to limit dummy coding these alleles as 0 or 1 in this regression model example, instead of allowing values of 0,1,or 2?
... This is not homework its just an example I found online. They are testing association between HLA alleles and some binary disease [here][1] in the data frame they have col `DQDRa1` and `DQDRa2` for haplotypes of HLA gene DQDR. It can be 10 different alleles which they recode into a number of dumm ...

Comment: C: logistic regression using HLA alllelic data
... To expand on this, how would it look if you did have covariate (sex). For example say I have a multialleleic locus with three possible snps: data <- data.frame("snp1"=c(runif(n=150, min=0,max=2), c(runif(n=50, min=0,max=2))), "snp2"=c(runi ...

What is the smallest number of cases you can have in a GWAS before interpretation starts becoming troublesome
... Lets say you had 100,000 samples, but were looking at some super rare diseases. At some point I would think even given the huge overall sample size that the number of cases makes interpretation hard, even if some really small p values are obtained via GWAS. is 5 cases 99,995 controls ridiculous? ...

Is there anyway to get a unix parallel command to write to standard output
... `parallel bcftools stats chr{}.bcf | grep "number of records:" | cut -f 4 > chr{}.txt ::: {1..22}` This does not seem to work for me, I have encountered similar issues with bcftools utilities and gotten around it by specifying my output with `-o` instead of `>` where possible, but obviously ...

Is this the correct notation for the logistic regression I am trying to describe? I am very new to statistics notation and LaTeX
... Let me know if this is off topic, I considered stack exchange, but I was worried about the domain specific content. I am performing association tests between a binary disease outcome a large set of multiallelic sites, each having *m* alleles with *Allele* representing the allelic dosage (0,1,2). I ...
