  1. For short hand notation, we used“MCH-2rounds” = MetaCRAM-Huffman with 2 rounds, “MCH-1round” = MetaCRAM-Huffman with 1 round. We also used the shortcut “MFComp” = MFCompress and “Align. %” refers to the percentage of reads aligned during 2 rounds and 1 round, respectively, for MCH-2rounds and MCH-1round
