The algorithm of image segmentation and parameters calculation for overlapping nuclear track image is studied.
本工作研究重叠核径迹图像分割和参数统计算法。
We have constructed a new matrix, TOPSSUM25, based on all-α protein fold core structure of proteins to improve the alignment of low-identity sequences.
在已有的BLOSUM取代矩阵算法基础上,定义了基于蛋白质折叠核心结构的序列-结构数据块;提出一种新的基于全α类蛋白质折叠核心结构的氨基酸残基取代矩阵——TOPSSUM25,用于提高低相似度序列的比对效果。
