Reference panel data to be used for GCTA-COJO

Reference panel data to be used for GCTA-COJO 0 I performed a genome-wide meta-analysis based on summary statistics from the four cohorts to identify significant loci. Next, I would like to perform a conditional analysis using GCTA-COJO to search for SNPs independent of significant lead SNPs. I know that GCTA…

How long does it take to carry out the GWAS workflow?

How long does it take to carry out the GWAS workflow? 0 Including these steps: 1) raw data format transformation for five companies 2) update positions for all SNPs to hg37 version 3) Quality control within companies 4) Pre-phasing (SHAPEIT2) and imputation (IMPUTE2) for all SNPs of each company 5)…

Understanding Conditional analysis

Understanding Conditional analysis 1 Hello, I’m new to data analysis and I’m having some trouble understanding the process and need help with a few questions. I am running a conditional analysis on chromosome 19 in relation to Alzheimer’s disease, I understand that conditional analysis tests whether SNPs have association independent…

Calculation of the GRM in GCTA

Calculation of the GRM in GCTA 0 Hi experts, I am new to the field. I have some questions wrt the calculation of the GRM: by using the GCTA software: Let’s say I have a population of genome data for N= 4800000, and the original genotype SNPs, and also the…
