WitrynaHere we have used the -strand_g option to provide a strand file to the program. This file tells IMPUTE2 how to align the allele coding between the study genotypes ( -g file) and the reference haplotypes ( -h and -l files). WitrynaComplement e.g. FileA C T FileB G A. In this case the probabilities in FileB are unchanged. Different e.g. FileA C T FileB G T. In this case the SNP is removed from the output. GTOOL is unable to determine the relative strand of AT,CG SNPs, which may lead to some SNPs of this type having missing data. A solution for this is being …
Population-specific genotype imputations using minimac or IMPUTE2 …
Witryna11 gru 2014 · It was beneficial to use this process of breaking the genotypic data into smaller regions because IMPUTE2 has been reported to have improved accuracy over smaller genomic regions and also separating data into segments helps allows for the parallelization of jobs over a multi-core compute cluster. http://pgxcentre.github.io/genipe/ flameco bakersfield ca
Population-specific genotype imputations using minimac or IMPUTE2
Witrynaanalogous to the IMPUTE2 definit ions of “type 2” and “type 0” SNPs, respectively. (Note that “type 1” SNPs occur only when more than one reference panel is used with IMPUTE2.) Lastly, we refer to study SNPs that do not occur in the reference as “study only” SNPs, or “type 3” in IMPUTE2. WitrynaIMPUTE2 Options: --impute2-bin BINARY The IMPUTE2 binary if it's not in the path. --segment-length BP The length of a single segment for imputation. [5e+06] --filtering-rules RULE [RULE ...] IMPUTE2 filtering rules (optional). --impute2-extra OPTIONS IMPUTE2 extra parameters. WitrynaIMPUTE2 definitions of “type 2” and “type 0” variants, respectively. (Note that “type 1” variants occur only when more than one reference panel is used with IMPUTE2.) Lastly, we refer to study variants that do not occur in the reference as “study only,” or “type 3” in IMPUTE2; these are also retained in imputation output. flameco bakersfield
