示例1: pdbBoxString
# 需要导入模块: import FUNC [as 别名]
# 或者: from FUNC import cos_angle [as 别名]
def pdbBoxString(box):
# Box vectors
u, v, w = box[0:3], box[3:6], box[6:9]
# Box vector lengths
nu, nv, nw = [math.sqrt(FUNC.norm2(i)) for i in (u, v, w)]
# Box vector angles
alpha = nv*nw == 0 and 90 or math.acos(FUNC.cos_angle(v, w))/d2r
beta = nu*nw == 0 and 90 or math.acos(FUNC.cos_angle(u, w))/d2r
gamma = nu*nv == 0 and 90 or math.acos(FUNC.cos_angle(u, v))/d2r
return pdbBoxLine % (10*FUNC.norm(u), 10*FUNC.norm(v), 10*FUNC.norm(w), alpha, beta, gamma)示例2: bbGetAngle
