Dear Megha. Since Eligos2 is not a Bioconductor package, you may have better luck trying Biostars instead. Still, some of these names are clearly based on genome coordinates and sequence names (first 7 fields). Then, some genetics descriptions, like major allele (most frequent), its frequency (major allele freq). adjPVal, a nominal P-value adjusted for multiple testing from the pval. OddR, odds ratio.
