Dear ChimeraX forum,

I am trying to do a sequence search with the Blast Protein tool (MacOS).

I have tried using various pdb structures/chains but am repeatedly getting the following

error:

"ValueError: not enough values to unpack (expected 2, got 1)"

from

".../blastprotein/pdbinfo.py", line 206, in fetch_info
entry, auth_cid = pcid.split('_')

What is the correct usage of Blast Protein?

Thank you!
