一种方法的晶体分析，以确定肌球蛋白头与特定的肌动蛋白位点在脊椎动物横纹肌相互作用描述。它是基于一个螺旋的傅里叶变换，其中出现的亚单位的概率周期性变化。它预测了在1/24和1/10.4 nm（-1）的层线的存在，这是在收缩和僵硬的脊椎动物横纹肌中实验观察到的，表明肌凝蛋白头部与肌动蛋白上的特定位点相互作用，但仍然保持其平均14.5 nm的轴向周期性。
A method of crystallographic analysis to identify myosin heads interacting with specific actin sites in vertebrate striated muscles is described. It is based on a Fourier transform of a helix in which probability of occurrence of subunits varies periodically. It predicts the presence of layer-lines at 1/24 and 1/10.4 nm(-1) which are experimentally observed in contracting and rigor vertebrate striated muscles, showing that the myosin heads are interacting with specific sites on actin but are still maintaining their average 14.5 nm axial periodicity.
