Modeller脚本build_profile.py无法获得正确的输出

Question

9用于蛋白质结构建模，通过它在python2.3上运行的方式，我之前已经进行了安装，当我运行脚本时，输出不是正确的，它应该是所有蛋白质序列的总称，而y仅获得第一个序列而我应该做的只是获得脚本的正确输出而已]

from modeller import*

log.verbose()
env = environ()

sdb = sequence_db(env)
sdb.read(seq_database_file='pdb_95.pir', seq_database_format='PIR',
     chains_list='ALL', minmax_db_seq_len=(30, 4000), clean_sequences=True)

sdb.write(seq_database_file='pdb_95.bin', seq_database_format='BINARY',
      chains_list='ALL')

sdb.read(seq_database_file='pdb_95.bin', seq_database_format='BINARY',
     chains_list='ALL')

aln = alignment(env)
aln.append(file='Brn3a.ali', alignment_format='PIR', align_codes='ALL')

prf = aln.to_profile()

prf.build(sdb, matrix_offset=-450, rr_file='${LIB}/blosum62.sim.mat',
      gap_penalties_1d=(-500, -50), n_prof_iterations=1,
      check_profile=False, max_aln_evalue=0.01)

prf.write(file='build_profile.prf', profile_format='TEXT')

aln = prf.to_alignment()

aln.write(file='build_profile.ali', alignment_format='PIR')

并且输出为

>P1;Bra
