I am trying to use the modeler comparative tool in Chimera to model the structure of a protein (in fasta format) by another similar proteinís structure (in pdb format).

I first associated this sequence (in fasta) with the corresponding chain in the pdb, and I used the modeller comparative tool to model the structure.


However, Iím getting this error: _modeller.SequenceMismatchError: read_te_291E> Sequence difference between alignment and pdb :


From the log window, I didnít get any other details beyond the above error. 

Does anyone know how I can figure out what is going wrong?


Thank you!

I really appreciate it!
