I've been using Zea_mays.B73_RefGen_v4.dna.toplevel as reference genome for my analysis. At the same time, I need to use maize HapMap file? Does anyone used B74 RefGenv4 and HapMap3? I'm having trouble to connect CyberDuck to acquire data from Cyverse iPlant platform. What is the easier or alternative way to acquire HapMap data in the local machine?
