I am going to generate a monomer from one single Template (tseq1) by modeller. But there one problem is arised. I have a only one template. According to the basic tutorial of modeller.. I made alignment file like this, (where tseq1 is single template file)

from modeller import *

env = environ()

aln = alignment(env)

for (pdb, chain) in (('tseq1', 'A')):

m = model(env, file=pdb, model_segment=('FIRST:'+chain, 'LAST:'+chain))

aln.append_model(m, atom_files=pdb, align_codes=pdb+chain)

aln.malign()

aln.malign3d()

aln.compare_structures()

aln.id_table(matrix_file='family.mat')

env.dendrogram(matrix_file='family.mat', cluster_cut=-1.0)

That time it was failed to run by showing the following error

"ValueError:too many values to unpack" .

can anyone tell me where is the problem?

Thank you.

Best Regards.
