2.2 Illumina short-read sequencing
Chinese walnut was sequenced on the Illumina HiSeq X Ten platform using 20Kb libraries. The Illumina sequencing raw reads were processed with SOAPnukev1.5.6 to removing adapters or low-quality bases with the parameters is ā€˜-n 0.01 -l 20 -q 0.1 -i -Q 2 -G -M 2 -A 0.5 –d’. Finally, 62.87 Gb of clean reads were used to assemble after assessment and error correction (Table S1).
