Hi, I am trying to help a labmate who is using DiffBind to do a PCA analysis on some ATAC-seq data that she generated. I have experience with PCA but not with this specific software. How can we retrieve the PCA loadings/eigenvalues for each individual for each PC? I am used to using other PCA tools that allow you to retried the spreadsheet of loadings/eigenvalues in addition to plotting PC's 1-10 against each other. As far as I can tell DiffBind allows you to plot PC1, PC2, and PC3 against each other but does not provide the actual numbers, nor does it provide access to any further PC's. Any help with this would be greatly appreciated.
