Hello,

I am trying to use the modeler comparative tool in Chimera to model the structure of a protein (in fasta format) by another similar protein’s 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, I’m getting this error: _modeller.SequenceMismatchError: read_te_291E> Sequence difference between alignment and pdb :

From the log window, I didn’t 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!

Best,

Zoey
