Please help me to rectify the error in mod9v2

 

My script

 

from modeller import *

log.verbose()
env = environ()

#-- Prepare the input files

#-- Read in the sequence database
sdb = sequence_db(env)
#sdb.read(seq_database_file='C:\Program Files\Modeller9v2\modlib\pdball.pir', seq_database_format='PIR',chains_list='ALL', minmax_db_seq_len=(30, 4000), clean_sequences=True)

#-- Write the sequence database in binary form
#sdb.write(seq_database_file='C:\Program Files\Modeller9v2\modlib\pdball.bin', seq_database_format='BINARY', chains_list='ALL')

#-- Now, read in the binary database
sdb.read(seq_database_file='C:\Program Files\Modeller9v2\modlib\pdball.bin', seq_database_format='BINARY',
         chains_list='ALL')

#-- Read in the target sequence/alignment
aln = alignment(env)
aln.append(file='p17787.fas', alignment_format='FASTA', align_codes='p17787')

#-- Convert the input sequence/alignment into
#   profile format
prf = aln.to_profile()

#-- Scan sequence database to pick up homologous sequences
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)

#-- Write out the profile in text format
prf.write(file='build_profile.prf', profile_format='TEXT')

#-- Convert the profile back to alignment format
aln = prf.to_alignment()

#-- Write out the alignment file
aln.write(file='build_profile.ali', alignment_format='PIR')
aln.check()

error what i have got
