Fig. 8From: Spark-based parallel calculation of 3D fourier shell correlation for macromolecule structure local resolution estimationThe K-V format based optimized fine-grained 3D array partition algorithm in Spark for 3D local resolution estimation. TB stand for triple block, TB=(x,y,z), where x, y, z is start coordinate of window traversing density map. 0, c, d, k are partition number, and 0 ≤ c ≤ d ≤k, k is the largest partition number. List of sequence numbering and start coordinates of window traversing are transformed into RDD. 3D sub-array pair are acquired by cutting 3D array using each partition data and side length of window, and calculated for gaining 3D local FSC and resolutionBack to article page
