Comment: C: Genesis: doubts with admixMAPMM
... No, not the way you've set it up here. It is possible to use three separate GDS files instead of a combined one, where each GDS file stores the local ancestry values in the "genotype" node. Then you would create the `GdsGenotypeReader` object with the default value of `genotypeVar="genotype"`. In th ...

Comment: C: Genesis: doubts with admixMAPMM
... I'm afraid I don't understand your specific question about the data structure above. The example in the manual page is somewhat misleading; if you have three ancestries total, you should only test two of them. I've updated the example here: https://github.com/UW-GAC/GENESIS/blob/master/man/admixMap. ...

Answer: A: Genesis: doubts with admixMAPMM
... The `admixMapMM` function is deprecated, and has been replaced by the `admixMap` function in current versions of GENESIS. However, I think your questions apply equally to the old and new versions. 1. The `show` method for a GdsGenotypeReader object displays all the information in the GDS file, rega ...

Answer: A: VCF file does not include snp.id, can I still run SNPRelate for Relatedness Anal
... When the GDS file is created, `snpgdsVCF2GDS` automatically generates a unique integer ID for each variant. This is what you would use to identify variants in SNPRelate functions. ``` snp.id <- read.gdsn(index.gdsn(genofile, "snp.id")) sample.id <- read.gdsn(index.gdsn(genofile, "sample.id")) ...

Answer: A: betas for binary outcome
... You have two options for calculating betas for binary outcomes. Option 1) refit the null model including the genotypes for the variant of interest as a covariate. This is a good option if you only need betas for a small number of variants. You can use `SeqVarTools::altDosage` to get the alternate a ...

betas for binary outcome
... Question asked via email: I am currently working on a project with a binary outcome, and need to report beta coefficients (representing the log-odds increase per copy of the minor allele), confidence intervals, and odds ratios for each variant. I am using a SeqVarGDSClass object with a SeqVarIterat ...

Answer: A: PCA axis description SNPRelate
... Yes, "principal component (PC)" and "eigenvector" mean the same thing. The element `$eigenvect` has the sample eigenvectors (each row corresponds to a sample). To obtain the SNP loadings, use the function `snpgdsPCASNPLoading`. ...

Comment: C: GENESIS pcrelate() write gds file doesn't work
... You only need to use `king2mat` to import results from the command-line version of KING (where `file.kin0` and `file.kin` are the paths to text files output by that software). If you are using `snpgdsIBDKING`, you already have the matrix in `king$kinship`. ...
