from Bio.PDB import *
parser=PDBParser()
structure=parser.get_structure('cal1','3CLN.pdb')
model=structure[0]
chain=model["A"]
hse=HSExposure()
expca=hse.calc_hs_exposure(model,option='CA3')
print expca[chain[40]]
当我执行此代码时,我收到此错误:
File "D:\python\Core\pdb_2.py", line 6, in <module>
hse=HSExposure()
TypeError: 'module' object is not callable
它出什么问题了?
