The file format is very simple: first five columns are chr, start, end, reference allele, observed allele, the sixth column (functional score) is optional. Running with MKL¶ If you've built DyNet to use MKL (using -DMKL or -DMKL_ROOT), Python sometimes has difficulty finding the MKL shared libraries. I have the following symmetric matrix, B: -0. Eigenvalues and eigenvectors can be selected by specifying either a range of values or a range of indices for the desired eigenvalues. My "opinion" pertains to numpy with MKL.
