I am beginner of modeller when i do basic homology modeling i got error
as follows
read_te_291E> Sequence difference between alignment and pdb :
Just like the error message says, your template structure's sequence (in
the PDB file, ATOM and/or HETATM records) must match that in your
alignment file exactly. In this case the sequence doesn't even seem
similar. Are you sure you used the right PDB code and chain?
